When an item has the tracking dimension group setup as do not allow blank issue, it would cause an issue for a PO return. If the PO has been received and right away need to return, since the package is not opened, batch number cannot be tracked on return PO.
It would be nice to breakdown the Blank Issue Allowed and Blank Receipt Allowed into more details to have separate configuration for return orders. This will provide more flexibility on tracking dimension controls.
