i have not so much experienced in CO-PA. my client company is using SAP ECC 6.O EHP5 and pre-defined record types in CO-PA.
client want to know why the line items screen layout of KE21N is different by record types. currently, when the record type, H, was entered, user-defined characteristics were displayed in screen. when the others were entered, all characteristics were displayed.
pls let me know how are they controlled on KE21N screen.
