Select Option in ABAP Module Pool Programming: A Step-by-Step Guide

 In ABAP Module Pool programming, selecting options typically involves creating input fields or selection screens for users to choose from. Here's a basic guide on how to implement option selection in an ABAP Module Pool program:

  1. Define Selection Screen Elements: You'll typically define selection screens using ABAP statements like PARAMETERS or SELECTION-SCREEN. These statements allow you to create input fields, checkboxes, radio buttons, etc., for users to select options.
  2. Capture User Input: After defining the selection screen elements, you need to capture the user input. This can be done either directly in the flow logic of the module pool or by handling user actions such as pressing a button to trigger the processing of selected options.
  3. Process Selected Options: Once you have captured the user's selections, you can process them according to your program's logic. This could involve querying a database, calling function modules, or performing calculations based on the selected options.
  4. Display Results: Finally, display the results of the processing to the user, either on the same screen or on subsequent screens.

Steps for Creating Select Option in Module Pool :-

  • Step 1 :- Create a Module Pool Program in ABAP Editor.



  • Step 2 :- Navigate to SE80 by clicking on object list display.



  • Step 3 :- Create a main screen 100.



  • Step 4 :- Double click on the program.

  • Step 5 :- We will have to create a selection screen there, so follow the below code.



    • Here, we have created a selection screen on a sub screen 200 and we can call it on our main screen.

  • Step 6 :- Now, we are require to call our selection screen into the .screen 100.

    • Create a sub screen area on the layout of screen 100.



    • Call the sub screen into the sub screen area.





  • Step 7 :- Create a transaction code for our program.



Code :-

*&---------------------------------------------------------------------*
*& Modulpool ZAR_SELECT_OPTION
*&---------------------------------------------------------------------*
*&
*&---------------------------------------------------------------------*
PROGRAM ZAR_SELECT_OPTION.

DATA : lv_ono type ZAR_ORDER_NUMBER.
SELECTION-SCREEN : begin of screen 200 as SUBSCREEN.
SELECT-OPTIONS : s_ono for lv_ono.

SELECTION-SCREEN : END OF SCREEN 200.

*&----------------------------------------------
*&End of Program
*&-----------------------------------------------------

Execute the Program



  • You can see we are getting the select option

Understanding Different Types of SAP Function Modules: Normal, RFC, and Update

  1. Normal/Regular Function Module :- It can be called inside the system. Here Pass by value + Pass by reference both is fine. 2. RFC Function Modules :- You can call from same system or from another possible. In RFC function module you can only have pass by value. In the same system if you are going to add the DESTINATION NONE’ while calling the RFC then it’ll be called in separate session. 3. UPDATE Function Modules :- This is generally used to update the database record. Update Function Module can be called from the same system. ( Background RFC / trfc / grfc ) This is used to achieve generally the SAP LUW. Some time we use from performance perspective also. When COMMIT WORK gets executed then Update starts getting executed. Important Questions on Update Function Modules :- When Update function Module gets Triggered ? ON COMMIT WORK IF a update function module gets failed, under which transaction we can see that ? OR What is the T-Code for moni

Unlocking SAP ABAP Secrets: Interactive Classical Reports with GET CURSOR, At User Command, and a Comparison of HIDE Statements

Image
 Welcome back everyone, We were discussing about the interactive classical reports, so let’s continue it. Interactive Classical Reports- GET CURSOR :- In Interactive Classical Reports, GET CURSOR statement is used to create secondary list according to cursor position. The parameter FIELD provides the name of an output field. The parameter VALUE provide the output value. Syntax : GET CURSOR FIELD <lv_field> VALUE <lv_value>. In the above syntax - the field name and field value will be returned in to variables lv_field and lv_value respectively. Requirement :- If you remember, In our last two blog, We have been displaying the order header table in a basic list and order item table in the secondary list. We have used SY-LISEL and HIDE statements to achieve the requirement. Now, we have to use the get CURSOR to achieve the same to same requirement.

Mastering ABAP: A Step-by-Step Guide to Function Modules and Groups for Modularized Programming

Image
  Function Modules :- It is a modularization technique. The transaction code to create a function module is SE37. To create a function module, we need to create a function group. Function Group :- Function group is a container for the function modules. The transaction code to create a function group is SE80. A function group can store up to 99 function modules. Requirement :- let’s create a function module for sum of two numbers. 1. Creation of function group :- Step 1 :- Go to SE80 transaction code → Object Navigator. Step 2 :- From the drop down select function group. Step 3 :- Give a name of function group. Step 4 :- press enter. Step 5 :- Click on yes a popup screen will appear. Step 6 :- Give short description → press enter → Assign package and transaction request and press enter. Step 7 :- Right click on function group and click on activate to activate the function group. Step 8 :- You will see two includes, will be added after ac
