When goods are returned, you differentiate between rack jobber goods and your own goods.

Returns of rack jobber goods from consumers are processed by using a minus sign or the ‘Reversal’ goods movement type (252/K). This posting is made automatically when POS sales are processed.

Returns of rack jobber goods to the rack jobber vendor only need to be posted in the R/3 System if Inventory Management is active. If you post the goods, use movement type 502/K.
