Not able to add items of Purchase Orders on an Inbound Shipment

Issue:

The item lines are not available when the Purchase Order is selected in the Inbound Shipment Record even though the Purchase Order is visible in the given role.

Solution:

To fix this problem users may try the following: 

1. Edit the missing Purchase Order. 
2. Close the item lines that are not available on Inbound Shipments using the Closed column on the item line. 
3. Click Save. 
4. Edit the Purchase Order. 
5. Reopen these lines. 
6. The Purchase Order can now be selected on the Inbound Shipments page using the Add PO Items button. 
7. Use the checkbox to add full PO’s

This issue is also seen in the POs created through CSV import.

Another option: 

1. Navigate to missing Purchase Order > Actions > Make Copy.
2. The new Purchase Order will now appear in the Inbound Shipment page using the Add PO Items button. 

Reason for the missing Purchase Orders: 

There is a chance that lines from the Purchase Orders which are not showing may have previously been attached to another Inbound Shipment. To prevent this, you may delete any Inbound Shipments that were not fully processed.
