• What is the cause and solution for SAP error message MECP009 - Account assignment for item & already exists ?

  The SAP error message MECP009 ("Account assignment for item & already exists") typically occurs in the context of purchasing documents, such as purchase orders or purchase requisitions. This error indicates that there is an attempt to create or modify an account assignment for an item that already has an existing account assignment.
  Cause:
  
  Duplicate Account Assignment: The most common cause of this error is that the item in question already has an account assignment (e.g., cost center, internal order, project, etc.) associated with it, and the system does not allow multiple account assignments for the same item.
