POS Interface - Outbound: Implicit Deletion 
Use
Objects in the POS system are usually deleted using a direct request.
However, if the main EAN/UPC of an article changes, the R/3 system does not usually know the old main EAN/UPC, which is needed to delete the article in the POS system. This would mean that, over the course of time, a large amount of unused data would build up in the POS systems.
For this reason, POS outbound has a function for implicit deletion, which automatically creates deletion records if they are needed.
