Identify the warehouse
Applies To: Microsoft Dynamics AX 2012 R3, Microsoft Dynamics AX 2012 R2, Microsoft Dynamics AX 2012 Feature Pack, Microsoft Dynamics AX 2012
If a warehouse has been transferred to the purchase header, or selected manually, the warehouse will also be transferred to the individual purchase lines. However, if the item on the purchase line has a mandatory warehouse, that warehouse will be transferred to the purchase line, instead.
If no warehouse is specified on the purchase header, the default warehouse (not necessarily the mandatory warehouse) for the item is transferred to the Warehouse field on the purchase order line.
At any point, you can change the value of the warehouse field manually on the purchase header.
