3799794 - Purchase Requisition creation/update fails with WBS validation error using External WBS ID

Symptom

  • After update 2608, externally created purchase requisitions via interface /MMPUR - PREQNIN - 00001 fail when WBSElement contains the external WBS element ID.
  • Error shown in message monitoring: "Ensure the value for WBS Element doesn't exceed 8 characters."
  • The process now accepts only the internal WBS element ID; external IDs that previously worked are rejected.

Environment

SAP S/4HANA Cloud Public Edition 2608

Reproducing the Issue

  1. Send a purchase requisition through interface /MMPUR - PREQNIN - 00001 with PUR_REQ_ACCT_ASSIGNMENT-WBSELEMENT populated with an external WBS element ID.
  2. Open Message Monitoring (Emergency Correction) for the interface run and review the log.
  3. Observe the error: "Ensure the value for WBS Element doesn't exceed 8 characters."

Cause

The current behavior after update 2608 requires the internal WBS element ID; external WBS element IDs are rejected due to an 8-character validation.

Resolution

  1. The solution of this issue is currently under investigation. Please follow this KBA for updates.
  2. Workaround: Provide the internal WBS element ID in PUR_REQ_ACCT_ASSIGNMENT-WBSELEMENT for PR creation/update via /MMPUR - PREQNIN - 00001.
  3. Use the Enterprise Project OData API to determine the internal WBS element ID from the external ID. Refer to: Enterprise Project (API_ENTERPRISE_PROJECT_SRV).
  4. Adjust the integration mapping so that the internal WBS element ID (8 characters) is sent in WBSElement.
  5. Reprocess the messages and confirm in Message Monitoring that PR creation/update completes without the WBS element length error.
