• What is the cause and solution for SAP error message GL531 - Object number already exists ?

  The SAP error message GL531 ("Object number already exists") typically occurs when you are trying to create a new object (such as a General Ledger account, cost center, or other master data) that has an identifier (object number) that already exists in the system. This can happen in various SAP modules, including Financial Accounting (FI) and Controlling (CO).
  Cause:
  
  Duplicate Entry: The most common cause is that the object number you are trying to create is already in use by another object in the system.
