Cannot Add or Update AP Invoice Distribution of PO Matched Invoices

Cannot change the charge account if PO has a destination type = Inventory or shop floor. This means that AP must use the accrual account

If user were allowed to change the account on the invoice, this would cause the accrual account to be out of balance. As a result the application restricts the user from changing the account at this point in time.

The user would need to discard the invoice line - which would reverse the invoice distribution in question. Then the user would need to correct the PO so the destination item was not inventory or shop floor. Then re-match the invoice.

This is intended functionality
