• What is the cause and solution for SAP error message IUUC_MAIN102 - Table count for &1 finished in sender system (RFC destination &2) ?

  The SAP error message IUUC_MAIN102 typically occurs during the process of data replication or data transfer between systems, particularly in the context of SAP Landscape Transformation (SLT) or SAP Data Services. This error indicates that there is a mismatch or issue with the table count in the sender system, which is being referenced through a Remote Function Call (RFC) destination.
  Cause:
  
  
  Table Count Mismatch: The error suggests that the number of tables being processed in the sender system does not match the expected count. This could be due to:
  
  Tables being added or removed in the source system.
  Incomplete or failed initial load of data.
  Configuration issues in the SLT setup.
  Network issues affecting the RFC connection.
  
  
  
  RFC Destination Issues: There may be problems with the RFC destination configuration, such as incorrect settings, authorization issues, or connectivity problems.
  
  
  Data Replication Configuration: The configuration for data replication might not be set up correctly, leading to discrepancies in the expected table count.
  
  
  Solution:
  
  
  Check Table Configuration: Verify the configuration of the tables in the SLT system. Ensure that all necessary tables are included in the replication setup and that there are no discrepancies between the source and target systems.
  
  
  Review RFC Destination: 
  
  Check the RFC destination settings in transaction SM59. Ensure that the connection is correctly configured and that the connection test is successful.
  Verify that the user credentials used for the RFC connection have the necessary authorizations.
  
  
  
  Monitor Data Replication: Use transaction SLT_MONI to monitor the data replication process. Look for any errors or warnings that might indicate issues with specific tables or the overall replication process.
  
  
  Reinitialize Replication: If the issue persists, consider reinitializing the data replication for the affected tables. This may involve stopping the replication, clearing the data, and starting the initial load again.
  
  
  Check Logs: Review the logs for any additional error messages or warnings that could provide more context about the issue. You can check the SLT logs in transaction SLG1 for relevant messages.
