Function Module Exit Part 2

 

  • We have discussed what are Customer Exit and their different types as well.
  • Also, In the Previous parts we have seen how we can find the function Module Exit for our requirement through debugging.
  • In this part, we will see how to find function module using another technique.

Suppose, we want to find function module exit for our VA01 transaction code.

Steps to find Customer Exit ( Function module Exit ) :-

  • Step 1 :- Go to VA01 transaction code.

  • Step 2 :- Click on system → status.



  • Step 3 :- Copy the name of the program.



  • Step 4 :- Now go to SE38 ( ABAP Editor ) transaction code and select the Attributes radio button.



  • Step 5 :- Click on display, it will return you the package name.



  • Step 6 :- Copy the package name and Go to SMOD transaction code.



  • Step 7 :- Click on utilities → find.



    • Click on execute button.


  • We can see we have a lot of Customer Exit available here, which also contains the Customer Exit for out requirement which is Sold to Party.

  • Step 8 :- Double click on Sold to Party Customer exit.



    • It will show all the function module exit , menu exit and customer exit if they are available.

Steps For Implementing Customer Exit :-

  • Step 1 :- Go to CMOD transaction code.



  • Step 2 :- Provide the project name and click on create button.



  • Step 3 :- Click on enhancement assignment and provide the name of the customer exit that we have found for our Sold to Party.



  • Step 4 :- Click on the Components tab, it will show us the components of the above given customer exit.



  • Step 5 :- Click on activate button to activate the implementation of our customer exit.



Writing the logic for Sold to Party Function Module Exit.

  • Step 1 :- Copy the name of the above function module exit and go to SE37 transaction code.



    • We can see we have a exporting parameter, E_KUNNR which we can use for transporting purpose.

  • Step 2 :- Go to source code and open the given include in change mode and write the below logic.



Testing the Implementation :-

  • Step 1 :- go to VA01 transaction code and give the below order type.



    • Press enter.


    • We can see the Sold to Party is getting auto populated.

Note :-

  • Always remove the code from function module exit after practicing it.

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

Image
  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. Code :- ************************************************************* *Start of Program *Declaring Strcutrure

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
