• What is the cause and solution for SAP error message WRF_APC394 - You cannot remove supplier assignment, a dateline exists for the item ?

  SAP Error Message:
  
  WRF_APC394 – "You cannot remove supplier assignment, a dateline exists for the item."
  
  Cause:
  This error occurs when you attempt to remove or change a supplier assignment for a material or item in the system, but there is already a dateline (deadline or scheduling line) associated with that item for the supplier. In other words, the system prevents you from deleting or modifying the supplier assignment because there are existing scheduling agreements, delivery schedules, or planned orders linked to that supplier for the item.
  The "dateline" here typically refers to scheduling lines or delivery dates that are tied to the supplier assignment. Removing the supplier assignment without first addressing these scheduling lines would lead to inconsistencies in procurement or production planning.
  
  Solution:
  To resolve this error, you need to:
  
  
  Check for existing scheduling lines or delivery schedules:
  
  Go to the relevant transaction (e.g., ME33L for scheduling agreements, ME23N for purchase orders) and check if there are any open scheduling lines or delivery schedules for the supplier and item combination.
  
  
  
  Delete or close scheduling lines:
  
  If possible, delete or close these scheduling lines or delivery schedules that are linked to the supplier assignment you want to remove.
  
  
  
  Check for planned orders or production orders:
  
  Verify if there are any planned orders or production orders referencing the supplier assignment. These may need to be deleted or adjusted.
  
  
  
  After clearing all dependent scheduling lines or orders, try removing the supplier assignment again.
  
  
  
  Related Information:
  
  This error is common in SAP Materials Management (MM) and Production Planning (PP) modules where supplier assignments are linked to scheduling agreements or planned procurement.
  The system enforces this check to maintain data integrity and avoid orphaned scheduling lines or procurement documents.
  If you are unsure about which scheduling lines or documents are causing the issue, you can use standard SAP reports or transaction codes like:
  
  ME2L (Purchase Orders by Vendor)
  ME33L (Display Scheduling Agreement)
  MD04 (Stock/Requirements List) to check planned orders or purchase requisitions.
  
  
  Always ensure that removing a supplier assignment does not disrupt ongoing procurement or production processes.
  
  
  Summary:
  
  
  
  Aspect
