Function documentationThird-Party Order Processing with Product Substitution

 

In service parts management it is common to substitute products, to react to constant changes to products with regard to their function. For example, obsolete service parts are replaced by new versions of the same service part. Products can also be substituted if they are not in stock.

In third-party order processing with product substitution you can allow the external supplier, under certain conditions, to exchange one product with another if it is not available in their stock.

Prerequisites

  • The system configuration for service parts management is active. You can find more information about this in SAP CRM Customizing, at Start of the navigation path Customer Relationship Management Next navigation step Transactions Next navigation step Basic Settings Next navigation step Activate System Configuration for Service Parts Management End of the navigation path.

  • SAP SCM Extended Warehouse Management is activated.

  • You use the availability check with SAP SCM Advanced Planning and Optimization (SAP APO).

    In SAP APO, you must have created an interchangeability group for the product that the external supplier can replace with another product. The product, substitute product, and the quantity are defined in the interchangeability group.

    In the SAP Easy Access Menu for SAP SCM, choose Start of the navigation path Advanced Planning and Optimization Next navigation step Master Data Next navigation step Application-Specific Master Data Next navigation step Product and Location Interchangeability Next navigation step Maintain Interchangeability Group End of the navigation path (transaction /INCMD/UI).

    You can find more information about interchangeability groups in SAP Library for SAP SCM, by choosing Start of the navigation path SAP Advanced Planning and Optimization (SAP APO) Next navigation step Master Data Next navigation step Application-Specific Master Data Next navigation step Master Data for Product and Location Interchangeability End of the navigation path.

Features

In third-party order processing, SAP APO determines an external supplier as the source of supply for an order item. This supplier delivers the product directly to the customer in its place.

The purchase order is updated in SAP ECC with the supplier confirmation or the shipping notification. A subitem is created for the new product in the purchase order. A message is also sent to SAP CRM, whereby the product is replaced by the new product in the sales order in the appropriate third-party item.

When the supplier confirmation or the shipping notification is posted using EDI, SAP ECC checks, via SAP APO, whether the external supplier is authorized to substitute the product with a different product.

Restrictions

You can only execute a one-to-one product substitution with simple quantity factors. This means that product A can only be replaced by product B, not by multiple products, and one piece of product A can only be replaced with one piece of product B.
