• What is the cause and solution for SAP error message IUUC_MAIN079 - Table &1 is not a cluster table in system &2 ?

  The SAP error message IUUC_MAIN079 indicates that the system is trying to perform an operation on a table that is expected to be a cluster table, but the specified table is not defined as such in the system. This error typically arises in the context of data replication or data transfer processes, particularly when using SAP Landscape Transformation (SLT) or similar tools.
  Cause:
  
  Table Type Mismatch: The operation is being attempted on a table that is not a cluster table, but the system expects it to be one. This can happen if the configuration or the data model is incorrect.
  Incorrect Configuration: The configuration settings in the SLT or data replication setup may be pointing to the wrong table or expecting a different table structure.
  Data Model Changes: If there have been changes to the data model (e.g., a table was changed from a cluster to a transparent table), the replication setup may not have been updated accordingly.
  
  Solution:
  
  Verify Table Type: Check the definition of the table in question (Table &1) using transaction SE11 (Data Dictionary). Ensure that it is indeed a cluster table if that is what is expected.
  Review SLT Configuration: If you are using SLT, review the configuration settings to ensure that the correct tables are being replicated and that the settings align with the current data model.
  Adjust Data Model: If the table has been changed from a cluster table to a transparent table, you may need to adjust your replication strategy or update the configuration to reflect this change.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SLT or the data replication tool you are using for any known issues or additional configuration steps.
  Check for SAP Notes: Look for any relevant SAP Notes that might address this specific error or provide guidance on how to resolve it.
