• What is the cause and solution for SAP error message IUUC_MAIN166 - Check for inactive and partly active tables completed; no tables found ?

  The SAP error message IUUC_MAIN166 indicates that the system has completed a check for inactive and partly active tables, but it did not find any tables that meet the criteria. This message is typically related to the SAP Landscape Transformation (SLT) replication process, which is used for real-time data replication from source systems to target systems.
  Cause:
  
  No Inactive or Partly Active Tables: The primary cause of this message is that there are no tables in the source system that are currently inactive or only partially active. This could mean that all tables are active and functioning correctly.
  Configuration Issues: There may be configuration issues in the SLT setup that prevent the system from recognizing any inactive or partly active tables.
  Replication Setup: The replication setup might not have been properly configured to include certain tables, leading to the absence of any tables to check.
  
  Solution:
  
  Verify Table Status: Check the status of the tables in the source system. Ensure that there are indeed tables that are inactive or partly active. You can do this by using transaction codes like SE11 (Data Dictionary) or SE14 (Database Utility).
  Check SLT Configuration: Review the SLT configuration settings to ensure that the relevant tables are included in the replication setup. You can do this in the SLT configuration transaction (usually LTRC).
  Activate Tables: If you find any tables that are inactive, consider activating them if they are needed for replication.
  Review Logs: Check the SLT logs for any additional error messages or warnings that might provide more context about the issue.
  Consult Documentation: Refer to SAP documentation or notes related to SLT and the specific error message for any additional troubleshooting steps or recommendations.
