Update No. of Packages on Outbound Delivery with IDOC
I'm using IDOC for picking process of outbound delivery. Everything is working fine. But my client is asking me for update on delivery header, the field "Number of packages" located at Picking tab. But the function module that standard idoc uses for update picking (SD_IDOC_INPUT_PICKING) doesn't have either workarea or parameter available for change this field. Also, the input help refers to this field to be automatically determinated by system. So i'm a little confused on how to update this field. Anyone know how to achieve this?
Thanks and regards
