  The SAP error message CNV_IUUC_DB_CONN089 typically occurs during data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services. This error indicates that there is an issue with creating a logging table due to an invalid index column.
  Cause:
  
  
  Invalid Index Column: The error suggests that one or more columns defined as index columns in the logging table are not valid. This could be due to:
  
  The column does not exist in the source table.
  The column is not suitable for indexing (e.g., it may be of a data type that cannot be indexed).
  There may be a mismatch in the data types or lengths between the source and target tables.
  
  
  
  Database Constraints: There may be constraints or limitations in the underlying database that prevent the creation of the index.
  
  
  Configuration Issues: Incorrect configuration settings in the SLT or data migration setup can lead to this error.
  
  
  Solution:
  
  
  Check Table Definitions: Verify the structure of the source table and ensure that all index columns defined in the logging table exist and are valid. Check for:
  
  Correct data types.
  Proper lengths and precision.
  
  
  
  Review SLT Configuration: If you are using SLT, review the configuration settings to ensure that the logging table is set up correctly. Pay attention to:
  
  The mapping of fields.
  The definition of index columns.
  
  
  
  Database Compatibility: Ensure that the database you are using supports the data types and indexing methods you are trying to implement. Consult the database documentation for any limitations.
  
  
  Adjust Index Columns: If necessary, modify the index columns in the logging table definition to ensure they are valid. This may involve:
  
  Removing invalid columns.
  Replacing them with valid ones.
  
  
  
  Check for Existing Tables: If the logging table already exists, check if it has been created correctly. If not, you may need to drop the existing table and allow the system to recreate it.
