How can we confirm the packing if the following error ‘Invalid item!’ occurs ?

Cause:
System shows the error ‘VTQCPACK, Invalid item!, Item Stock Maintenance is Item wise, Packing Details cannot be made for such item’ on confirm for the particular item selected in packing which are non serialized.
Remedies:
Users will have to remove the items from the packing transaction. That is from the issue and receipt detail screen of packing transactions as the items are non serialized. If the item stock option in item master is ‘no stock maintenance’ then the item cannot be used in packing.
