Hi,

I have worked on a lot of report programs,but when it comes to Module pool I get really confused.I now that the main difference between the 2 is,Module pool need a Tcode to be executed.Kindly help me with this query.How do I go about creating a Module pool program.

Thanks

Module-pool programs need tcode to exeute.These are type 'I' programs so you cannot execute directly.Plz check the below links you will get a clear idea how to work with module pools.....Just like your report programs this is also quite easy..

HI,

Module pools are directly created using the ABAP Editor and are introduced with the PROGRAM statement. With the exception of reporting event blocks and function modules, module pools can contain all processing blocks supported in ABAP and as many local classes as required. While they are executed, all events of the ABAP runtime environment may be triggered.

The most important technical attribute of a module pool is that it can only be controlled using screen flow logic. You must start them using a transaction code, which is linked to the program and one of its screens (initial screen). Another feature of these programs is that you must define your own screens in the Screen Painter (although the initial screen can be a selection screen).

When you start a program using a transaction code, the runtime environment starts a processor that calls the initial screen. This then calls a dialog module in the corresponding ABAP program. The remainder of the program flow can take any form. For example, the dialog module can:

· return control to the screen, after which the processing passes to a subsequent screen. Each screen has a following screen, set either statically or dynamically. Screens and their subsequent screens are components of freely definable screen sequences.

· call other screen sequences, selection screens or lists, from which further processing blocks in the ABAP program are started.

· call other processing blocks itself, either internally or externally.

· call other application programs using CALL TRANSACTION or SUBMIT.

It is appropriate to use module pools when you write dialog-oriented programs using a large number of screens whose flow logic largely determines the program flow of screen sequences.

bharat.

1. Go to se38 create a Z program, then select the type as Module Pool.

2. Now go to se51, give the same program name which u have created in the first step and give some screen number.

3. Then go to Layout design the screen by putting some text fields and push buttons, then save and activate it and come back.

4. Then u will see 2 processes one is called as PBO and the other one is PAI.

5. In PBO u will write all the code which u want to process before the screen gets displayed on to the screen when u run the transaction code created.

6. In PAI u will write the code which will be triggerred when u click on some button after the screen gets displayed.

7. Then activate whole program.

8. Create a Transaction code starting with Z in se93.

9. Then in that screen give the program name in which u have written ur code and screen number.

10. Then save it.

11. Now run the program by giving the Tcode which you have created.

Go through these sites also u will get an idea.
