Short Text
Central order block for customer
Definition
Indicates if sales order processing is blocked for the customer in all sales areas (company-wide, for example).
Use
If you block sales order processing, the block counts for the following partner functions of the customer:
- Sold-to party
- Ship-to party
- Payer
If you want to process an order where the ship-to party differs from the sold-to party, and the ship-to party is blocked, you cannot process the order.
Example
You can define different kinds of block, according to the needs of your organization. You can, for example, automatically block all free of charge deliveries and credit memo requests for a certain customer, pending manual approval before further processing can take place.
Regards,
