Batch Splitting
in Purchasing 
Use
As of Release 4.6C, the batch split implemented in an inbound delivery can be displayed in the PO confirmation overview and taken into account at the time of goods receipt.
For the batch split to be taken into account as the time of goods receipt, you must specify in Customizing for Purchasing for the confirmation category "Inbound delivery" that the ensuing GR is to be effected on a confirmation-related basis ( GR assignment indicator).
