Receive eDoc Over-tolerance AdHoc Product lines

As per the release on March 12 & 14th users should now be able to receive eDoc over-Tolerance deliveries however users are still getting the same error message.

'Cannot submit when a difference occurs'

when the order has ad-hoc products in it. 

Adhoc products are occuring regularly with our wine suppliers as they change the product code with every vintage they release and send whichever year they have in stock not necessarily the one we have ordered.

Users are unable to receive these invoices in Adaco desktop and just get an error message rather than being able to put on-hold. The only way we can receive these in currently is for an admin/finance to 'unapply the invoice'
