The following indicators for reference documents are processed:

001	Order number of customer
002	Order number of vendor

This segment is extremely important for the processing of the order change. The sales document to be changed in the system is identified via the entry of reference document numbers. There are two possibilities:

Identification via the customer purchase order number

This option requires that the customer purchase order number exists once in the system under the respective partner number of the sold-to party. A customer order number that exists more than once leads to error message /AFS/IDOC 006 in the inbound processing. An invalid customer order number leads to error message VG151.

Identification via the order number

As an alternative to the customer order number, the order number stored in the system can also be used for the identification of the document. If this order number cannot be determined, you will see the error message /AFS/IDOC 014.
