Smart SAP Assistant

• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION258 - Creation of index on table &1 failed (&2). ?

  The SAP error message CNV_IUUC_REPLICATION258 indicates that there was a failure in creating an index on a specific table during the data replication process. This error is typically 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.
  Causes:
  
  Existing Index Conflicts: An index with the same name may already exist on the target table, causing a conflict.
  Insufficient Permissions: The user executing the replication may not have the necessary permissions to create indexes on the target table.
  Table Locking: The target table may be locked by another process, preventing the creation of the index.
  Database Constraints: There may be constraints or limitations in the database that prevent the creation of the index (e.g., insufficient space, incompatible data types).
  Replication Configuration Issues: There may be issues with the SLT configuration or settings that affect index creation.
  
  Solutions:
  
  Check Existing Indexes: Verify if an index with the same name already exists on the target table. If it does, you may need to drop it or rename the new index.
  Review Permissions: Ensure that the user account used for the replication has the necessary permissions to create indexes on the target database.
  Check for Locks: Investigate if the target table is locked by another process. You can use database tools or SQL queries to check for locks and resolve them.
  Database Space: Ensure that there is enough space in the database to accommodate the new index. If space is limited, consider increasing the database size or cleaning up unnecessary data.
  Review SLT Configuration: Check the SLT configuration settings to ensure that they are correctly set up for the replication process. This includes verifying the connection settings and replication settings.
  Consult Logs: Review the SLT logs for more detailed error messages that can provide additional context about the failure.
