SAP Error Message - Details

• Message type: E = Error

• Message class: PPEFLO - Messages for iPPE Application Object FLO

• Message number: 421

• Message text: You must assign a storage location at supply area &1 (&2)

What causes this issue?

No storage location is assigned to supply area &V1& in location &V2&.
This represents an inconsistency of the master data. Such an
inconsistency can occur if the supply area is deleted in R/3 and the
deletion is transferred to the APO. However, the usage of the supply
area in an iPPE line object remains.

System Response

When generating the PDS, within the iPPE line explosion, the system uses
the deleted supply area and the location to search for an issuing
storage location which no longer exists as it has been deleted. Without
an issuing storage location, errors occur during confirmation.

How to fix this error?

Maintain the master data of the supply area within the location and
transfer the new supply area to the APO System.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
