The design of this business function does not allow planned delivery costs for MAA service purchase order items. When posting the goods receipt for MAA purchase order items, the system checks the data to be posted for consistency. If this data is not consistent, the posting of the goods receipt terminates with error message M7 599. This message should prevent data inconsistencies.
If you enter a return delivery or reversal for an item whose “delivery completed” indicator has already been set, so that the delivered quantity falls below the under delivery tolerance limit, the “delivery completed” indicator is automatically reset.
