Process documentation Triggering Third-Party Order Processing from the Sales Order 


If you do not know the vendor responsible for delivering particular goods when you create a sales order, or source determination for a particular product fails in SAP SCM Advanced Planning and Optimization (SAP APO) (that is, it does not return any results for vendors), you can use this process to trigger creation of a purchase requisition in SAP ECC. You can then convert the purchase requisition manually into requests for quotations (RFQs) to potential external vendors. The external vendors accept the purchase order that results from the sales order, and are responsible for fulfilling the sales order.

In third-party order processing, you do not deliver to the customer yourself, but rather transfer delivery of the goods to another vendor. This vendor sends the products directly to the customer, and invoices for goods delivered. A sales order can consist partly or entirely of third-party items.


In addition to CRM Enterprise, the following minimum system requirements apply:

  SAP SCM 5.0

  SAP ECC 6.0

The system configuration for service parts management is active. For more information about this, see the SAP Implementation Guide (IMG) for Customer Relationship Management at Transactions ® Basic Settings ® Activate System Configuration for Service Parts Management.

SAP recommends that you create your own transaction type and item category for this process. You have to have assigned action profile CREATE_PREQ to this item category. This action profile is used to call up method TPOP_CREATE_PURCHASE_REQUISITI which triggers creation of the purchase requisition.

In addition, an ATP profile must not be assigned to this item category, that is, a Global Available-to-Promise cannot be triggered via the item category, because a Global Available-to-Promise would otherwise be triggered repeatedly without returning any results.


When the product is assigned to an item category for which an ATP profile with ATP has been assigned in the SAP APO system, you must assign this product to an item category that does not trigger a Global ATP in SAP APO .

For more information, see the SAP Implementation Guide (IMG) for Customer Relationship Management at Transactions -> Basic Settings -> Define Item Categories.

Process Flow

When a customer orders a product that you cannot currently deliver from your own stock, and your Global Available-to-Promise in SAP SCM does not return any results for vendors, you can create a purchase requisition in SAP ECC. You can then create requests with reference to this purchase requisition, and send them to external vendors who potentially have the required product in stock. These external vendors would then deliver to the customer in your place. You can choose the appropriate vendors from the quotations sent back to you.

The business processes run in the following order:

This graphic is explained in the accompanying text

  1.  Create sales order (SAP CRM)

A user-defined communication channel can trigger creation of a sales order.

  2.  Source determination unsuccessful (SAP SCM, SAP APO)

Source determination cannot be carried out successfully, that is, determination does not return any results for vendors.

  3.  Select action Create Purchase Requisitionmanually (SAP CRM)

If a source of supply is not found in SAP APO for the order item created, you can trigger an action that creates a purchase requisition in SAP ECC by selecting Create Purchase Requisition in the toolbar.


The action can only be executed if you are using an item category that you have assigned a particular action profile to (see section ‘Prerequisites').

  4.  Create requests for quotation with reference to purchase requisition (SAP ECC)

For each vendor, create a request for quotation with reference to the purchase requisition. The RFQs are sent to the vendors via the message output in SAP ECC.

For more information about further processing of purchase requisitions, see SAP Library for SAP ECC at Logistics ® Materials Management ® Purchasing ® Purchase Requisitions or under Logistics ® Materials Management ® Purchasing ® Purchase Requisitions and Quotation ® Creation of RFQs.

  5.  Receive request for quotation (external vendor)

The vendors receive the RFQs and issue quotations for you. The quotations from the vendors are sent to you either via EDI or manually.

  6.  Issue quotation (external vendor)

  7.  Receive quotation (SAP ECC)

  8.  Accept or reject quotation (SAP ECC)

You call up transaction /SPE/CRM_QUOT in SAP ECC. You choose the RFQs from the list of RFQs that already have a quotation (recognizable by the status Quotation Received), and meet your requirements with regard to quantity, delivery date, and price. You also choose the quantities to be delivered so that the quantities in the quotation match the quantity in the purchase requisition. You reject the remaining quotations and notify the respective vendors.

  9.  System creates subitems with reference to quotations (SAP CRM)

The accepted quotations are sent to SAP CRM, and the corresponding subitems are created for each quotation with reference to the quotation. The subitem contains the external vendor as the source of supply, and a link to the corresponding quotation.

  10.  You create the purchase order with reference to quotations (SAP ECC)
When you save, the purchase orders are created with reference to the quotations. Afterwards, the sales order is processed further as in third-party order processing.

The individual steps are logged in the document flow; amongst other things, the reference to the request for quotation is displayed.

  11.  Receive purchase order (external vendor)
