Introduction to Explicit Enhancement

 

  • Till, our previous part we have seen about Implicit Enhancements, from now on, we will discuss about Explicit Enhancements.

  • In case of Explicit Enhancement, we have a explicit point which can be available at any line in the program.

  • We will write the logic for our Explicit Enhancements using these points and sections.

  • We will discuss the difference between these Enhancements points and Enhancements sections later.



Let’s take a requirement for best understanding of Enhancement Point.

Enhancement Point :-

Requirement :-

  • We create a material using MM01 transaction code.





    • When we click on save button, our material will be created and we will get a message for the same.


  • Now, Our Requirement is that, Our Material number must contain any number from 1 to 9.

  • And if does not contains any number from 1 to 9, thee material should not be created and we should be getting a popup message that Material number must contain a number from 1 to 9.

Hint :-

  • Since, we are passing material number on the Create Material ( Initial Screen ). So, we PAI event will triggering on the screen for the same.

Solution :-

  • Step 1 :- Click on System of MM01 → Status on Create Material ( MM01 ).



  • Step 2 :- Double Click on the Screen number.



  • Step 3 :- In PAI, we can see we have this Module.



  • Step 4 :- Double click on this module and put a debugger in it.



  • Step 5 :- Now go back to MM01 transaction code and give the details and press enter.

  • Step 6 :- Debugger will hit and we will go to debugger screen where we can see, whatever material we are getting, we will getting it a variable RMMG1.



    • Now, we can use this variable for writing our logic for enhancement.

Writing Logic :-

  • Step 1 :- Go the above module in PAI for MM01 screen.



    • We will use this enhancement point for writing our logic.

  • Step 2 :- Click on the enhancement point and click on enhance button.



  • Step 3 :- Right click on enhancement point → Enhancement Operations → Create Implementation.

  • Step 4 :- Click on create button.



  • Step 5 :- Click on OK button and double click on it.



  • Step 6 :- We will write the logic here.



Check the Status :-

  • Go to MM01 and try to pass a material which does not contain any number, you will get the message.



    • Always undo the implementation after practice.

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
