I'm trying to find in all the PO objects where the screen data are filled in the data attributes. For instance, the attribute PO_ITEM_HASH_TABLE from CL_PO_ITEM_HANDLE_MM seems to hold the data. But I'd like to find exactly where it's filled in, and I can(t find out. It's just used in methodes GET_DATA and SET_DATA, and the constructor seems not to explicitly fill it.
Actually, my requirement is to get a custom Account Assigment element from stocked orders. That's mean that FI account assigment elements are not displayed, just FM's if you've set them in customizing. (the Account Assigment category in PO line is blank).
Note that I have created a new account assignment element within structure CI_COBL using FI customizing.
I've found a way to display my element somewhere near the display of the FM account assigment elements, but the value user enters is not sent to PAI. It looks like because it's not in the PO_ITEM_HASH_TABLE attribute.
If anyone has a clue,
