Screen Exit - Enhancement MM06E005 - Transfer input data back to program
I have implemented enhancement MM06E005 to create a subscreen on the PO header. I have created the screen and I see it on the POs tcodes (ME2#n). However, I can't figure out how to "save" the data that the user inputs. By save I mean bringing the data back to the calling program (tcode). When the PO is saved the input data goes away; it is there until the save. I realize that I am missing something but I can't figure how where/how to transfer the data in the FMs EXIT_SAPMM06E_007 and/or EXIT_SAPMM06E_008.
I have read the SAP documentation but that isn't much help. I also have a book from SAP on modifications/enhancements (from an SAP course) and that isn't of any help either.
