  The SAP error message EVAL_IV_HD002, which indicates a "Double key" issue, typically arises in the context of data evaluation or processing where a unique key constraint is violated. This can occur in various scenarios, such as during the creation or updating of records in a database table where a unique key is expected.
  Cause:
  
  Duplicate Entries: The most common cause of this error is the presence of duplicate entries in the database that violate the unique key constraint.
