PGI (goods issue) before TO/picking

Hi,

Is it possible post goods issue before creating and confirming transfer order? I would like work this way. With 916 storage type negative waiting for the transfer order; after confirm the TO the system should move the quantities from the corresponding stock bin to the negative 916.

Currently I receive the messages VL608 and VL609 when I try to post the goods issue before TO.

Tks.
