• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION281 - Create control tables failed for table &1 in Schema &2 ?

  The SAP error message CNV_IUUC_REPLICATION281 indicates that there was a failure in creating control tables for a specific table in a given schema during the data replication process. This error is typically associated with the SAP Landscape Transformation (SLT) replication process, which is used to replicate data from a source system to a target system.
  Cause
  The error can be caused by several factors, including:
  
  
  Missing Authorization: The user executing the replication may not have the necessary authorizations to create control tables in the specified schema.
  
  
  Database Issues: There may be issues with the database itself, such as connectivity problems, insufficient permissions, or database constraints that prevent the creation of the control tables.
  
  
  Existing Control Tables: If control tables already exist for the specified table and schema, the replication process may fail if it attempts to create them again without proper handling.
  
  
  Configuration Issues: Incorrect configuration settings in the SLT setup can lead to failures in creating control tables.
  
  
  Schema Mismatch: The specified schema may not be correctly set up or may not match the expected configuration for the replication process.
  
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Authorizations: Ensure that the user executing the replication has the necessary authorizations to create tables in the specified schema. This may involve checking roles and permissions in the database.
  
  
  Review Database Logs: Check the database logs for any errors or warnings that may provide more context about why the control table creation failed.
  
  
  Verify Existing Control Tables: Check if the control tables already exist in the specified schema. If they do, you may need to drop them or adjust the replication settings to avoid conflicts.
  
  
  Configuration Review: Review the SLT configuration settings to ensure that they are correctly set up for the source and target systems. This includes checking the connection settings, replication settings, and any relevant parameters.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes or documentation that may address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
  
  
  Re-run the Replication: After addressing the above points, try re-running the replication process to see if the issue persists.
