I want to create Idoc type ZMRESCR01 as an Extension of Basic Idoc type MRESCR01.
I have created the Segments that I want to add to the Basic type using transaction WE31.
When I try to extend the Basic Idoc type with transaction WE30, the error message "Action is not possible for generated idoctypes" appears.
In Note 913901, I have read that I can extend this Basic type using transactions BDFG and BDBG, but I can't find any documentation about how to do it.
Can you point me to any documentation or show me how to extend Generated Idoc types?
