Scenario
Trying to close a Purchase Order or Inbound Shipment since there is no expected Items anymore but the Purchase Order "Close" button is disabled.
Solution 1
Change the Purchase Order "Quantity" of the specific item/s to expected to receive only.
Solution 2
Or, change the Inbound Shipment's "Quantity Expected" same as the Quantity Received.
Note: There is no "Close" button showing on the Inbound Shipment because of the Partially Received status. User must receive the remaining stocks so that the status will automatically set to Closed.
