In third-part processing your company does not deliver the goods required by the customer. Instead you forward the request to an external vendor who then sends the goods directly to the customer and charges you for the goods. You then send the customer an invoice.
When the sales order is saved, a purchase requisition item is automatically created for each third-party relevant item schedule line in the sales order. This is controlled by the configuration settings of the item category and schedule line category determined for the item. The item category determination depends on the Item Category Group set on the material master record and the order type of the sales order. The item category can also be set manually in the sales order item.
The schedule line category is determined by the combination of the item category previously determined plus the MRP type specified on the material master. In the schedule line category the settings specifies that the purchasing order type must be a purchase requisition and that the purchasing item category must be set as third party. The schedule line category is not set as delivery relevant and also has no movement type entered as no delivery will be created with reference to the sales order.

The diagram Data Transfer for Third-Party Processing lists the most important data that is transferred from the sales order to the item of the purchase requisition when the sales order is saved. This data transfer is continued to the related purchase order when it is created from the purchase requisition.
When changes are made to a third-party item in a sales order (such as delivery date or order item quantity), these changes are automatically copied to the related purchase requisition as long as the processing status of the purchase requisition still allows this.
The purchasing item category is set not to require a goods receipt but is set to require an invoice receipt during the third-party process. Once the invoice receipt has been posted the sales order becomes due for billing. This is controlled by the billing-relevance indicator on the sales order item category. The customer billing document quantity is then equal to the quantity specified in the vendor invoice. The sales order is considered fully billed until the next invoice is received from the vendor and posted in the system. The quantity to be invoiced is then calculated as the invoice receipt quantity less the quantity previously billed to the customer.
