Field help (ITMDESSRH) 

The standard description for the product is initialized by the product description if it is a direct return (making no reference to any shipment).
If it is a return linked to a shipment the product description will be the product description entered in the delivery.

When the return comes from a direct supplier return (inter-site), the standard description will be inherited from the supplier return.
If the supplier has as origin a delivery, the standard description from the delivery will be reused.
