• What is the cause and solution for SAP error message IUUC_REPAIR030 - Table &1 unknown in CDC for Mass Transfer &2 in RFC Destination &3 ?

  The SAP error message IUUC_REPAIR030 indicates that there is an issue with the Change Data Capture (CDC) process, specifically related to a table that is not recognized in the context of a mass transfer operation. This error typically arises in scenarios involving SAP Landscape Transformation (SLT) or SAP Data Services when trying to replicate or transfer data from one system to another.
  Cause:
  
  
  Unknown Table: The error suggests that the specified table (&1) is not recognized in the CDC configuration for the mass transfer (&2). This could be due to:
  
  The table not being included in the replication setup.
  The table being deleted or renamed in the source system.
  A misconfiguration in the RFC destination (&3).
  
  
  
  Configuration Issues: There may be issues with the configuration of the SLT system or the RFC connection that prevents the system from recognizing the table.
  
  
  Authorization Issues: The user or service account used for the RFC connection may not have the necessary authorizations to access the specified table.
  
  
  Solution:
  
  
  Check Table Configuration:
  
  Verify that the table (&1) is included in the SLT configuration for replication. You can do this by checking the SLT configuration in transaction LTRC or LTRS.
  If the table is not included, you may need to add it to the replication setup.
  
  
  
  Verify Table Existence:
  
  Ensure that the table exists in the source system and has not been deleted or renamed. You can check this using transaction SE11 or SE16.
  
  
  
  Check RFC Destination:
  
  Verify the RFC destination (&3) to ensure it is correctly configured and points to the right target system.
  Test the RFC connection using transaction SM59 to ensure it is working properly.
  
  
  
  Authorization Check:
  
  Ensure that the user or service account used for the RFC connection has the necessary authorizations to access the table and perform the required operations.
  
  
  
  Reinitialize the Replication:
  
  If the issue persists, consider reinitializing the replication for the affected table. This may involve stopping the replication, making necessary adjustments, and then starting it again.
  
  
  
  Check Logs:
  
  Review the SLT logs for any additional error messages or warnings that may provide more context about the issue. You can find logs in transaction LTRC or LTRS.
