• What is the cause and solution for SAP error message CNV_IUUC_REPL_ADV_SE111 - Select only one row ?

  The SAP error message CNV_IUUC_REPL_ADV_SE111 ("Select only one row") typically occurs in the context of data replication or migration processes, particularly when using the SAP Landscape Transformation (SLT) Replication Server or similar tools. This error indicates that the system expected a single row to be selected from a database table or a result set, but multiple rows were returned instead.
  Cause:
  
  Multiple Rows Returned: The most common cause of this error is that a query or operation is designed to handle a single record, but the underlying data or the conditions applied to the query resulted in multiple records being returned.
  Incorrect Filtering: The filters or conditions applied in the selection criteria may not be specific enough, leading to multiple rows being selected.
  Data Integrity Issues: There may be issues with the data integrity in the source system, such as duplicate entries that violate the expected uniqueness of the data.
  
  Solution:
  
  Review the Query: Check the SQL query or the selection criteria being used. Ensure that it is designed to return only one row. You may need to add more specific conditions to narrow down the results.
  Check for Duplicates: Investigate the underlying data to identify if there are duplicate entries that should not exist. If duplicates are found, you may need to clean up the data to ensure that only unique records are present.
  Adjust Data Model: If the data model allows for multiple entries where only one is expected, consider adjusting the model or the logic to handle such cases appropriately.
  Debugging: If you have access to debugging tools, you can trace the execution of the process to see where the multiple rows are being generated and adjust accordingly.
