• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION139 - Change of source system table &1 requires conversion of target table ?

  The SAP error message CNV_IUUC_REPLICATION139 indicates that there has been a change in the structure of a source system table that requires a corresponding conversion of the target table in the context of SAP Landscape Transformation (SLT) replication. This typically occurs when there are changes in the source table, such as adding or removing fields, changing data types, or modifying the primary key.
  Cause:
  
  Schema Changes: The source table in the source system has undergone changes (e.g., new columns added, existing columns modified).
  Replication Configuration: The SLT configuration may not be updated to reflect these changes, leading to inconsistencies between the source and target tables.
  Data Type Changes: Changes in data types or lengths of fields in the source table that are not reflected in the target table.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Source Table Changes:
  
  Review the changes made to the source table in the source system. Identify what modifications have been made.
  
  
  
  Update SLT Configuration:
  
  In the SLT system, you may need to adjust the configuration to accommodate the changes in the source table. This can involve:
  
  Reinitializing the replication for the affected table.
  Adjusting the mapping of fields if necessary.
  
  
  
  
  
  Perform Table Conversion:
  
  Use the SLT transaction code LTRC to manage the replication settings. You may need to perform a conversion of the target table to align it with the new structure of the source table.
  You can also use the RS_LTRC_REPL_MAINTAIN report to maintain the replication settings.
  
  
  
  Reinitialize Replication:
  
  If necessary, you may need to stop the replication for the affected table and then reinitialize it. This will ensure that the target table is correctly aligned with the source table.
  
  
  
  Check for Errors:
  
  After making the necessary changes, monitor the SLT logs for any further errors or warnings to ensure that the replication is functioning correctly.
  
  
  
  Related Information:
  
  SLT Documentation: Refer to the official SAP documentation for SLT for detailed instructions on managing table replication and handling schema changes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or fixes related to this error message.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  LTRC: SLT Configuration and Monitoring
  SLT Replication Monitor: To check the status of the replication process.
  
  
  
  By following these steps, you should be able to resolve the CNV_IUUC_REPLICATION139 error and ensure that your SLT replication is functioning correctly.
