Hi OM,
Product warehouse task is the final Put away task at the time of Inbound or the 1st Pick task at the time of Outbound.
It contains the information of what product is to be moved, how much quantity has to be moved and where it has to be moved.
As EWM works with HU's and HU is mandatory for POSC, so all the movements apart from final putaway or 1st Pick task, are carried with HU, and the document which carries the information of the source and destination of HU movement, is called HU task.
1 HU can have many products and all can be moved from source to destination using single HU task.No separate task is required for product when it is packed in a HU.
Thanks.
