I had a question regarding the "Output message determination" for Picking-list and Packing-list for both MM level and WM level, what are the output types for them and how should i config them.
EK00 is used for special case pickings which may not apply to what you are looking for. Typically, LD00 under application V2 is used for picking list. This picking list output type can be used for both IM and WM levels.
However, for WM, the transfer order acts as a picking list since the bin level picks will appear on this form in lieu of the picking list generated via LD00. The configuration transsaction OMNU is the place where the transfer order output determination is maintained. For additional documentation on WM outputs, please use the following documentation:
WM -> Activities -> Define print control.
