• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION236 - Replication Suspended ?

  The SAP error message CNV_IUUC_REPLICATION236: Replication Suspended typically occurs in the context of SAP Landscape Transformation (SLT) replication. This error indicates that the data replication process has been suspended due to various reasons, which can include issues with the source or target systems, network problems, or configuration errors.
  Causes:
  
  Network Issues: Temporary network disruptions between the source and target systems can lead to replication being suspended.
  Configuration Errors: Incorrect settings in the SLT configuration can prevent successful data replication.
  Database Locking: If the source database is locked or undergoing maintenance, replication may be suspended.
  Resource Limitations: Insufficient resources (CPU, memory, etc.) on either the source or target system can cause replication to halt.
  Error in Data Transfer: If there are errors in the data being transferred (e.g., data type mismatches), replication may be suspended.
  Replication Queue Issues: Problems with the replication queue, such as being full or having unprocessed entries, can also lead to suspension.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the source and target systems. Test the connection and resolve any connectivity problems.
  Review SLT Configuration: Verify the SLT configuration settings to ensure they are correct. Check for any misconfigurations that could affect replication.
  Monitor Database Locks: Check if the source database is locked or undergoing maintenance. If so, wait for the maintenance to complete or resolve the locking issue.
  Resource Monitoring: Monitor system resources on both the source and target systems. If resources are low, consider optimizing performance or scaling up resources.
  Check Replication Queue: Use transaction codes like LTRC (SLT Monitoring) to check the status of the replication queue. Clear any errors or unprocessed entries.
  Error Logs: Review the SLT error logs for more detailed information about the cause of the suspension. This can provide insights into specific issues that need to be addressed.
  Restart Replication: In some cases, simply restarting the replication process can resolve the issue. This can be done through the SLT configuration interface.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LTRC (SLT Monitoring) and LTMOM (SLT Model Management) for monitoring and managing replication.
