• What is the cause and solution for SAP error message KG351 - Entry & is already contained in Table & ?

  The SAP error message KG351 ("Entry & is already contained in Table &") typically occurs in the context of the Controlling (CO) module, particularly when dealing with cost elements, cost centers, or internal orders. This error indicates that there is an attempt to create or modify an entry that already exists in the specified table.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that the system is trying to insert a record that already exists in the database table. This could happen during data entry, data migration, or when running a program that processes data.

  Modify the Entry: If the entry already exists and you need to update it, consider modifying the existing record instead of trying to create a new one.
