Instead of user exits?

Question

Is there any other method to meet the customer requirements instead of User Exits?

Answer 1

Hi,
BADIs is other method to meet the customer requirements instead of User Exits
i will explain the <b>difference between USER EXIT and BADI.</b>
The major difference between Badi and customer user exit is badi can be built by class and methods means it’s purely relates to OOPS (Object oriented) and with single badi can contain multiple methods, so that one badi can contains screen, field, function exits.
<b>For BADI:</b>
Suppose let say imepl1 has created for badi00 and this badi00 contains 3 methods, in which you activated one method. Now you can also create one more implementation say imepl2 has to be create for badi00 to be use for method 2.
<b>Conclusion: One BADI can implement multiple times but not Customer exit of project.</b>
And coming to <b>customer user exit</b>, I will explain scenarios
There is requirement you need to be use the enhancement or function exit which already activated under one Project name.
As you know one project can contains multiple enhancements and enhancement also contains multiple function exits.
1)       Suppose if you are going to be add one more enhancement in existing project which already implemented by some one. Now you have to go to existing project and go to ‘Enhancement assignment’ and click on change mode, add new enhancement then by default it will display all function exits which it contains. Then as you know to add the code into include under particular function exit and activate include and come back and press activation button under enhancement screen and come back to initial screen ie CMOD screen press ‘active’ button. This is one way to active or implement the existing project by multiple times.
2)       second scenario is suppose if  enhancement contains multiple function exits out of one user exit already activated by some one of written some code. Now you need to be writing or use other function exits under the same enhancement of same project. In this case you can’t  activate the function exit under separate project instead you need to be use the same project, by writing code in particular include by create it. This is one way you can use the same project as well as same enhancement, but creating or activating new function exit.
3)       Third scenario is if you want to add the code to the existing function exit. Suppose if some one else already activated one function exit with code. Now requirement has come to add some more functionality to the same exit under the same enhance, and same project. This is like modifying the existing report or program.
<b>Conclusion: You can’t activate one enhancement under two projects</b>
<b> Reward with points if helpful.</b>
