We are creating purchase order in the system and assigning a supplier.

If the Customer address is blank, and we confirm the purchase order; then a incomming shipment record is generated with the assigned supplier.

If the customer address is assigned, and we confirm the purchase order; then a incomming shipment record is generated but the assigned supplier is the customer we assign in the purchase order.

I suppose this should not be the normal behavior.

Anybody has experience this issue ir know if i am doing something wrong?
