General Syntax of a Call transaction method

2013-01-13T20:09:00.002+05:30

Here you can find out the several parameter and their values while calling call transaction method

CALL TRANSACTION <tcode>
MODE <mode>
UPDATE <update>
Where,
<tcode>: Transaction code
<bdc_tab>: Internal table of structure BDCDATA
<mode>: Display mode
<update>: Update mode

MODE parameter above is used to specify whether data transfer processing should be displayed as it happens. You can choose between three modes:

Mode	Description	Significance
A	Display all	All screens and the data that goes in them appear when you run your program
E	Display errors only	The transaction goes into display mode as soon as an error in one of the screens is detected. You can then correct the error
N	No display	All screens are processed invisibly, regardless of whether there are errors or not. Control returns to your program as soon as transaction processing is finished.

UPDATE parameter to specify how updates produced by a transaction should be processed.

Mode	Description	Significance
S	Synchronous	In this mode, the called transaction waits for any updates that it produces to be completed. The called transaction is able to return any update error message that occurs to your program.
A	Asynchronous	In this mode, the called transaction does not wait for any updates it produces to be completed. It simply passes the updates to the SAP update service.
L	Local update	If you update data locally, the update of the database will not be processed in a separate process, but in the process of the calling program

How to use a multipane UI element in Webdynpro ABAP

2013-01-03T07:31:00.001+05:30

Multipane UI element can be used in case of creating a dynamic ui elements in webdynpro abap. Suppose you have to create a set of UI elements based on certain entries dynamically, then you can simply create that set under a multipane and then bind that multipane with that data holding table node.

Then in run time this pane will create similar set as per the table entries.

Here we will try to create a application where on clicking the button the same UI text node will add in the screen.

From the rootuielementcontainer create a multipane UI element.

Then under that you can create your text UI elements like you do for any webdynpro application.

After binding you can see that in view section, the text will come 3 times automatically. Which means it is indicating that multipane is set properly for dynamic entries.

Next in the button on click, write the below code.

DATA lo_nd_node_counter TYPE REF TO if_wd_context_node.

DATA ls_node_counter TYPE wd_this->Element_node_counter.

DATA lt_node_counter TYPE wd_this->Elements_node_counter.

lo_nd_node_counter = wd_context->get_child_node( name = wd_this->wdctx_node_counter ).

ls_node_counter-increase_counter = ls_node_counter-increase_counter + 1.

append ls_node_counter to lt_node_counter.

lo_nd_node_counter->bind_table( new_items = lt_node_counter set_initial_elements = abap_false ).

Activate and execute the application. After execution first screen will be like this.

Now click on the button and you can see that same is getting added one by one.

Now you can create whatever in your mind and play with this UI element. This is a very useful UI element to handle complex dynamic web applications in ABAP.

BDC session method in sap abap

2012-12-25T20:02:00.001+05:30

In BDC Session method several transactions can be processed together. It actually submit the BDC session to batch processing and wait in the queue. You can view the result via transaction SM35.

There are three functional modules to be called from BDC Program for submitting the transactions for processing: BDC_OPEN, BDC_INSERT and BDC_CLOSE.

The most important aspects of the session method are:
• Asynchronous processing
• Transfer of data for multiple transactions
• Synchronous database update
• Generation of a batch input processing log for each session
• Sessions generation in parallel.
• Opening of a session by batch input program not possible until closure of the preceding session.

Pre-Exit, Post-Exit, Overwrite Exit methods in webdynpro abap

2012-12-08T14:03:00.000+05:30

Generally these methods are used in case of webdynpro abap enhancement scenario. You can easily enhance an existing application to modify some functions. E.g. you want to remove a button from a standard webdynpro screen. In such a scenario, you can enhance the standard webdynpro application and then remove the button. Now in this scenario when you go to that view controller methods tab, you can see 3 methods : Pre-Exit, Post-Exit, Overwrite Exit. These methods will provide you the flexibility to modify the standard screen logic.

Pre-Exit: This method will call before WDDOINIT method of that view.
Post-Exit: This method will call after WDDOINIT method of that view.
Overwrite Exit: This method will simply overwrite standard code and only follow the code written inside it.

So be careful while writing any logic in those methods.

Types of controller in webdynpro abap

2012-12-07T13:47:00.000+05:30

Controllers are the entry point into a webdynpro application. User can instruct the application via this controller only. Controllers holds all the logic and flow of the application and context hold the data. In an application there are 5 types of controller.

Component controller: This is the main controller and the only one for the application. You can also call it as a global controller. Whenever webdynpro application is called this controller instantiated first. All the major logic is hold by the this controller ans it is also visible to other controllers of that application.
Custom controllers: As the name suggests if the requirement need some extra functionality which component controller can not serve, then you can create a custom controller. Its completely optional. Generally if your component have many views and windows, then you can create multiple custom controllers to split the load. This is similar to modularisation technique in ABAP report.
Interface controller: This is also a default controller which creates in the webdynpro framework automatically. This controller is mainly use in-case you are importing some existing components functionality. This is called component usage.
View controllers: Every view is having a controller to collect data from component controller based on user request. That is view controller.
Window controllers: Similar to views every window is also have a controller to get data via inbound or outbound plugs.

The major data is always retrieved in the component controller context and later on with the help of view and window controller passes to views and windows.

Model View Controller (MVC) Architecture in Webdynpro ABAP

2012-12-06T13:25:00.000+05:30

This is the very basic concept of Webdynpro ABAP. In fact almost every interviewer will ask this question to test the basic concept about webdynpro abap. As the name suggests MVC architecture means a set up with a model, view and a controller to complete a webdynpro application.

Model is nothing but the flow of data retrieval for the application. Generally all the business logic is written here and whenever required model will return the data without thinking about how will it be displayed.

View is nothing but the screen what user will see. All the data from the model will display in the view with proper arrangements and customization. Thsi is similar to ABAP selection screen with output where user can choose their data and display.

For every webdynpro ABAP application there is a controller for that application. Controller will act as a back bone of that application which will pass data between user and application.

How to call an URL from webdynpro abap screen

2012-12-05T07:51:00.002+05:30

Calling an URL is nothing but hyper linking some text to an external link or website. This feature can be achieved in Webdynpro ABAP very easily. Simply create an Webdynpro ABAP application and insert a button or text in the screen. Now for that text or button create an on-click method.

In that method put the below code.

data lo_window_manager type ref to if_wd_window_manager.data lo_api_component type ref to if_wd_component.data lo_window type ref to if_wd_window.lo_api_component = wd_comp_controller->wd_get_api( ).lo_window_manager = lo_api_component->get_window_manager( ).

CALL METHOD lo_window_manager->CREATE_EXTERNAL_WINDOW EXPORTING URL = ' Enter Website Address Here' MODAL = ABAP_FALSE HAS_MENUBAR = ABAP_TRUE IS_RESIZABLE = ABAP_TRUE HAS_SCROLLBARS = ABAP_TRUE HAS_STATUSBAR = ABAP_TRUE HAS_TOOLBAR = ABAP_TRUE HAS_LOCATION = ABAP_TRUE RECEIVING WINDOW = lo_window.

lo_window->open( ).

Now activate your application and then test. You can see the text of button on the screen, as soon as you click on that button or text your given website will open in a new window.

Error Handling in Batch Input Method

2012-12-01T23:25:00.004+05:30

It is found that most problems usually fall into one of the following two categories:

Case 1:
Errors in the data conversion program or the presence of unexpected types of data or incorrect data in the legacy database are the possible external causes of this type of problem.
Within R/3, the causes for this type of problem include incorrect or incomplete customizing in an application.
E.g. A legacy data type may not have been foreseen in the check table entries made in application customizing.

Case 2:
Error in technical/programming problems. The data is entered by a batch input session by running R/3 transactions non-interactively.
Therefore, a typical technical or programming problem is the incorrect identification of one of the data fields in a transaction. OR
The conversion program may not fill a required data field or may have provided invalid values.

In case of an error in Call Transaction Method, Use Standard Function module 'FORMAT_MESSAGE'.

What is hook methods in web dynpro abap

2012-11-25T11:47:00.000+05:30

Hook methods are the default methods created by Webdynpro framework itself for every view, controller and context. Actually these methods trigger at run-time on various stages of a webdynpro life cycle. E.g. when you launch an application, there are methods where you can modify the screen elements at run-time. You can also check user input and validate. Also based on user action what should be next step can be decided. So these many functionality can be achieved by these hook methods.

There are many such method available in Webdynpro abap. You just have to find out the accurate one and write your code to achieve the functionality. Check out the list of such methods.

Use of supply function in webdynpro abap

2012-11-24T02:23:00.000+05:30

Supply function is another very useful meta option provided in Webdynpro ABAP node level. Generally if there are 2 dependent nodes and based on ones entry another will change, in such scenario supply function come in picture. This is nothing but a method only where you can write code.

Now here you can put the name of method and then double click on that and write the code. Whenever the parent node's lead selection changes, this method will trigger at run-time So the entry for the supply function is the lead selection data of the parent node. So this method will not at all trigger until the parent node is called in the run-time.

And one more thing is that, whenever you are going to use supply function method, you have to be sure that for the entry in the parent node there will be some entry in the sub-node so that supply function can fetch that data. Otherwise chances of error will be there.

Advantages of the BATCH INPUT method

2012-11-23T02:09:00.000+05:30

We already know that BDC techniques mainly classified in 2 categories. Batch input process and Direct method. Although each of them has its own benefit, but here is some advantages in Batch input method over Direct input method.

This method can process a large volume of data
It can be planned and submitted in the background.
No manual interaction is required when data is transferred.
Data integrity is maintained at whatever data is transferred to the table is through transaction Hence batch input data is submitted to all the checks and validations.

What is singleton property in webdynpro abap

2012-11-21T08:23:00.001+05:30

In Webdynpro ABAP singleton property is a very useful property of any context node, when there is parent node with a child node attached. Let's say you have a deep structure, where based on parent node entry you need several entries in the child node. Like a header and item table data concept.

Now when you check on this singleton property in the parent node, the every time the parent node lead selection changes the child node will contain the data related to parent node lead selection entry only. This actually improve memory usage at run-time.

E.g. For an airline company website you might have searched for a route's flight information. Now when you searched for a date, the list will display 4-5 entries with Airlines operating on that route. Now when your click on a particular Airline, then the flight schedule will display on screen. As soon as you change the Airline, the schedule will change. So here Airline companies are in parent node with singleton property checked, so when you clicked on them they just display the schedule of that Airline on that day.

Hope this will clear your doubts.

3 major techniques or methods in BDC

2012-11-21T02:01:00.000+05:30

Data can be transferred via BDC in 3 major techniques or methods:

1. Session method
2. Call transaction
3. Direct input.

Session method and Call transaction method come under Batch Input method. In this technique generally data is uploaded and create a session which later on executed and completed the data load.

Direct input method is the standard way of data loading in SAP system.

Types of data transfer in BDC

2012-11-19T01:31:00.000+05:30

As we have already learned that, with BDC data can be transferred from a SAP to non SAP ans also vice versa. This can be classified in 2 sections

• Outbound
• Inbound

1. Outbound: Transfer data from the Source system to Target system (External/Internal). Outbound is the data transfer from SAP R/3 system to another SAP R/3 or Non-SAP system. Here, Source system is always SAP.

2. Inbound: Transfer data from External System into SAP system. Inbound is the data transfer from SAP R/3 or Non-SAP system to SAP system. Here, Target System is always SAP.

But BDC itself is an inbound data transfer technique.

Why companies need BDC?

2012-11-18T02:01:00.000+05:30

When company decides to move to SAP from any other ERP, they have to transfer the existing data from old system to new SAP system. Without data no use of the new system. So here come BDC in picture to help the old data to migrate in new SAP system.

Now this data transfer can be done in 2 ways normally

1. all the data of old system will go at one go

2. Transfer data periodically from one system to another system

As technology help us in every aspect of life, why this data transfer will be done manually. The answer is BDC programming. Practically it is too tough to transfer data manually as the number of records is huge. And also chances of manual errors and tracking them are next to impossible.

So BDC is a very helpful tool which helps companies to transfer their old system data to newly implemented SAP system without any hassle.

Introduction to Batch Data Communication (BDC)

2012-11-17T20:56:00.000+05:30

Batch Data Communication (BDC) is a technique in ABAP technology to upload data from a system to SAP system. It can be sap to sap or non sap to sap.

BDC works through an ABAP program and works on the principle of simulating user input for transactional screen. User has to follow few steps and then data will be recorded from a physical file.

It is a uni-directional batch interfacing technique used for uploading data into SAP R/3.

BDC can transfer data from one SAP System to another SAP System or can transfer data from non-SAP System to SAP System too. Generally data is transformed in text file format which later on uploaded into SAP system via BDC program.

Finally the administrator has to process the job to complete the data upload, as by BDC it can create a session with all the data.

There are couple of types of techniques in BDC in case of data upload. That will be discussed gradually in coming tutorials.

Few points to keep in mind in case of Secondary Indexes

2012-11-16T16:00:00.001+05:30

When table contents change, indexes are readjusted

Slows down database insertion

Frequently accessed tables should not have too many indexes

Create indexes only when that index is likely to be used frequently

Indexes created may not be used to one's liking.

Determined by database optimizer by an algorithm

Indexes should have few common fields. Too many common fields would create problems for the optimizer

Use SQL Trace for determining indexes

What is implementation experience mean in SAP world?

2012-11-12T15:55:00.001+05:30

The most important part for any consultant in SAP is the implementation experience. Every ABAPer wants to work in a implementation project, so that they can get more developments and sharpen their knowledge. Even its good to work in a implementation project also.

When you try to change or switch your job, the very common question asked by the interviewer is How many implementation projects did you work? Even HR people or recruitment consultant who never had any experience in SAP asked such questions mostly. Anyway the answer they get from us is "I worked on 2-3 implementation project", just an example.

But do you really know that the actual meaning of the question is different. Even the HR people or even most of us don't know that.

Actually by implementation, some one want to ask you in how many actually implementation project did you involve? Whatever we do in our day to day work in offshore is a part of implementation. The actual implementation is done in the client site, mostly on site.

So if you have ever traveled to client site for implementation purpose, there you can face the real challenge of implementation. How the different programs were connected and how they behave in production. The clients reaction on every issue etc etc.

I think that should be count as a complete implementation experience, where you involved in development, support, integration and all other important phases of an SAP implementation.

How to use ABAP Online Debugging tool

2012-11-10T23:38:00.000+05:30

Debugging tool is a very useful tool for an ABAPer. You can simply put a break-point in ABAP code and then when you execute that program the above screen will appear for your program. Now you can do many things with this tool to investigate your issue line by line. Let's find out the most useful features pf this tool.

Single Step(F5): Executes the report line by line. This is useful if the user wants to see the program execute one line at a time.

Execute(F6): Processes all of the steps associated with one line of code. For example, one line of code may be a call to a subroutine. Execute will process that line without showing all of the activities inside the subroutine.

Continue(F7): This will help you to come out of a particular sub program of your main program without line by line code.

Continue(F8): Processes all statements until a break-point or the end of the program is reached. If no breakpoints exist, the system will execute the report in its entirety without stopping.

Use the the arrow buttons, or type in the line number required to move in the code display (page icons and page up and down keys can also be used)

To display the current statement (ie next statement to be executed) click the push-button next to the line number

Does SAP ABAP Certification guarantee a job in current market?

2012-11-08T20:12:00.002+05:30

SAP has become very hot technology these days. Right now in the current market scenario in ERP, SAP is the king. So ABAP is also the king, as it is the backend of any SAP module. But due to a good career prospect in SAP area, more and more people started engaging in SAP ABAP or you can say SAP from any background. Here we will point only to SAP ABAP.

ABAP is purely technical. Means you have to learn and think logically and really fast. ABAP is a huge language and believe me it will take your real hard work to learn the basic ABAP only. Even this is not the end, Advance ABAP topics are next. Basic ABAP is a must but not enough to get a job. You have to learn Web-dynpro ABAP, OOPs, Workflow to attract companies towards your CV. And the most challenging part in ABAP is you need more and more practice than theoretical knowledge.

So, the thing is industry require a talented and skilful ABAPer. Who has some real time experience with project work experiences. May be with some on-site exposure with real-time implementation experience. In such a scenario if you do ABAP certification, you will be benefited from that. But I think as a fresher Certification program will not add much value. Because you do not have that real-time on project experience, which ABAP certification cannot provide. And numbers of certified consultants are also increasing day by day. So obviously the value is getting diluted. But any SAP Certification program has its own value which is definitely very high comparing with a similar profile.

But ultimately knowledge is the only factor in any technology or sector. No one can stop you to get a job, if you can achieve complete command over technology.
