 Third-Party Order Processing by Source Determination

Purpose

In this process, you do not supply the customer yourself. Instead, you assign another supplier to deliver the products requested by the customer. Source determination within third-party order processing serves to determine procurement documents and valid suppliers.

Prerequisites

  • You have made the settings for source determination .

  • You have not specified a supplier as the source of supply in the order item in SAP Customer Relationship Management (SAPCRM). If you specify a supplier in SAPCRM, Global ATP in SAP Advanced Planning and Optimization (SAPAPO) only checks the validity of this supplier. If the supplier is valid, SAPAPO confirms the requirement.

  • You carry out source determination for the original requirement quantity from SAPCRM. If the requirement quantity of one or more subitems changes in SAPCRM, no new source determination takes place in SAPAPO.

  • The following prerequisites must be fulfilled for Global ATP to find valid suppliers:

    • The requirement date/time lies in the validity periods of the transportation lanes.

    • The requirement quantity is not greater than the lot size (provided you have defined lot sizes in transportation lanes).

Process

  1. SAPCRM triggers the following in SAPAPO:

    • Source determination using the ATP profile

      A requirements profileis assigned to the ATP profile in SAPAPO. The system uses this to determine check instructions. In the check instructions, you have activated third-party order processing either directly or by means of the rules-based ATP check.

    • Scheduling

  2. The system performs source determination in SAPAPO to find valid suppliers. As part of source determination, the system checks whether there are valid info records, contracts, or scheduling agreements (depending on the value you have chosen in the check instructions for the source determination method).

    Note Note

    Scheduling agreements are only valid in source determination if they show an open release quantity.

    End of the note.

  3. The system compiles a list of valid suppliers.

    You can restrict the list using either the condition technique or the Business Add-In (BAdI) /SAPAPO/TPDS_SODET.

  4. The system confirms the full requirement quantity for the first valid supplier, irrespective of the amount of supplier stock. The system does not perform an availability check for the supplier stock.

  5. SAP CRM creates a subitem in the sales order.

  6. After you save the sales order, SAPCRM triggers the following actions depending on the latest sales order creation date/time:

    • A purchase order in SAPECC

    • A planned purchase order in SAPAPO

      You can use the Convert Planned Purchase Orders report to convert the planned purchase order into a purchase order. For more information, see Conversion of Planned Purchase Orders .

Dependencies

Backorder Processing

  • Backorder processing only considers third-party items for which there is still a planned purchase order.

  • So that backorder processing can determine third-party items, you create a selection criterion Supplier in the filter.

  • If you want to perform batch backorder processing for main items of third-party items, you set the Rule Evaluation (Again) indicator.

    Rounding

The system rounds the requirement quantity of third-party items before source determination using the rounding procedurefor the input or the substitute location product.
