• What is the cause and solution for SAP error message KO212 - The entry already exists in table & ?

  The SAP error message KO212 ("The entry already exists in table &") typically occurs when there is an attempt to create a new entry in a database table where a record with the same key already exists. This can happen in various contexts, such as when creating cost centers, internal orders, or other master data entries in SAP.
  Cause:

  Incorrect Input: The user may have mistakenly entered the same key or identifier that is already in use.

  Data Cleanup: If duplicates are found due to data migration or other issues, you may need to clean up the data by removing or consolidating duplicate entries.
