Explicit Enhancement Using Enhancement Section in MM01

 

  • In the previous part, we saw how we can use Explicit Enhancement using Enhancement Point.
  • We have taken a real life scenario where we saw, how to make changes in SAP functionality for MM01 transaction code.
  • Now, In this part we will take a requirement and we will see how we can perform explicit enhancement using Enhancement section.

Difference between Enhancement Point and Enhancement Section :-

  • In case of enhancement section, we will see some default implementations as well.
  • In case of Enhancement point, we can only add additional codes, and we cannot replace the existing code.
  • But In case of Enhancement section we can change or replace the existing SAP code.

let’s take a requirement to Understand Enhancement Section

Requirement :-

  • Suppose, I go to MM01 transaction code.

  • And I pass the Industry Sector and Material Type and I am not passing the material number.



  • Now, As Soon as I Press enter, I want to know which material number will be created.

Solution :-

  • Step 1 :- Go to MM01 transaction code.

  • Step 2 :- Go to System → Status → Double click on screen number.

  • Step 3 :- Go to PAI and double click on module INTERNAL_MATERIAL_NUMBER_GET.

  • Step 4 :- In Enhancement Section we have this given function module.



  • Step 5 :- This function module is basically generating the material number, So we need to write the logic for it.

  • Step 6 :- Click on the enhancement section → click on enhance button.

  • Step 7 :- Right click on enhancement section → enhancement operations → create implementation.

  • Step 8 :- Click on create button.

  • Step 9 :- Pass a name and click on OKAY button.



  • Step 10 :- Now, we can see all our default implementation in the enhancement section has been copied and pasted in our enhancement, and whatever logic we will write here will be implemented.

  • Step 11 :- Go to SE91 transaction code and write a message as shown below.



  • Step 12 :- go back the enhancement and write the message as shown below.\



    • Activate the code.

Checking the Enhancement :-

  • Step 1 :- Go to MM01 transaction code and pass the below details.



  • Step 2 :- Press enter.



Important Question :-

  1. What is the SPOTS in the Explicit Enhancements ?



    • SPOTS are the container for our explicit Enhancements which consist Enhancement Point and Enhancement Section.

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
