Hi Nagaraju,
Actually,for every T-code,SAP has provided a lot of BADIs where the customer can write their own codes depending
upon the functionality required.
In order to find the BAD for a particular T-code,go to the T-code SE24 and type in cl_exithandler and click on
Display.
You will get a list of methods in that class,double click on the Get_Instance method from the list.
you will get the code for that method.Scroll down and you will find one of the parameters "Exit Name" there.Put a
breakpoint on that function module and press F8.
In the debugging mode,double click on the Exit Name to get the value contained in it.You will see the first BADI
provided in that T-code.
Note down this and then keep on pressng the F8 and noting down the BADIs being displayed.
Now ,you will have to find out the BADI which fits your requirement.
Now,it is not required to opy that BADI into ZBADI.Instead it is better to create a new implementation for this
BADI.
Go to the T-code SE18 and see its definition.
Now,go to the T-code SE19 and create a new implementation and write the code there.
Once done,activate that implementation and the BADI also.
Now run the T-code and debug the code that you have written.You can modify the code accordng to your requirements.
In case you have any further clarifications,do let me know.
