• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION035 - Error while deleting logging tables ?

  The SAP error message CNV_IUUC_REPLICATION035 typically occurs during the data replication process, particularly when there is an issue with deleting logging tables. This error is often associated with the SAP Landscape Transformation (SLT) replication process, which is used for real-time data replication from source systems to SAP HANA or other target systems.
  Cause
  The error can be caused by several factors, including:
  
  Database Locking Issues: The logging tables may be locked by another process, preventing deletion.
  Insufficient Authorizations: The user executing the deletion may not have the necessary permissions to delete the logging tables.
  Corrupted Logging Tables: The logging tables may be corrupted or in an inconsistent state.
  Configuration Issues: There may be misconfigurations in the SLT setup or replication settings.
  Database Constraints: There may be foreign key constraints or other database constraints preventing the deletion of the logging tables.
  
  Solution
  To resolve the CNV_IUUC_REPLICATION035 error, you can try the following steps:
  
  
  Check for Locks:
  
  Use database tools or transaction codes (like SM12 in SAP) to check if there are any locks on the logging tables. If locks are found, identify the process holding the lock and resolve it.
  
  
  
  Verify Authorizations:
  
  Ensure that the user executing the deletion has the necessary authorizations to delete the logging tables. You may need to consult with your SAP security team.
  
  
  
  Check Table Integrity:
  
  Run database consistency checks to ensure that the logging tables are not corrupted. You can use transaction codes like SE14 (Database Utility) to check and repair tables.
  
  
  
  Review SLT Configuration:
  
  Check the SLT configuration settings to ensure that they are correctly set up. This includes verifying the connection settings, replication settings, and any relevant parameters.
  
  
  
  Manual Deletion:
  
  If the logging tables are not needed, you may consider manually deleting them using SQL commands. However, this should be done with caution and ideally in a test environment first.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes in the SAP Support Portal that may address this specific error. SAP frequently updates their knowledge base with solutions for known issues.
