• What is the cause and solution for SAP error message IUUC_TAB205 - Log table not found for '&1' ?

  The SAP error message IUUC_TAB205 indicates that a log table for a specific table (represented by &1) is not found. This error typically occurs in the context of SAP Landscape Transformation (SLT) or when using SAP Data Services, where data replication or transformation processes are involved.
  Cause:
  
  Missing Log Table: The log table that is supposed to track changes for the specified table does not exist in the database. This can happen if the initial setup of the SLT or data replication was not completed correctly.
  Incorrect Configuration: The configuration for the data replication might be incorrect, leading to the system not being able to find the necessary log table.
  Table Deletion: The log table may have been deleted or not created due to an error during the initial setup or replication process.
  Transport Issues: If the system was recently transported, the log table might not have been included in the transport request.
  
  Solution:
  
  
  Check Log Table Existence: Verify if the log table exists in the database. The log table typically has a naming convention that includes the original table name, often prefixed with LT or similar.
  
  For example, if the original table is MY_TABLE, the log table might be LT_MY_TABLE.
  
  
  
  Recreate Log Table: If the log table is missing, you may need to recreate it. This can often be done by reinitializing the data replication for the specific table.
  
  Use transaction code LTRC to access the SLT configuration and check the status of the table.
  If necessary, delete the existing configuration for the table and set it up again.
  
  
  
  Check Configuration: Review the SLT configuration settings to ensure that everything is set up correctly. This includes checking the source and target system connections and ensuring that the table is included in the replication setup.
  
  
  Consult Logs: Check the SLT logs for any errors or warnings that might provide more context on why the log table is missing. This can help identify if there were issues during the initial setup.
  
  
  SAP Notes: Look for relevant SAP Notes that might address this specific error. SAP frequently updates its knowledge base with solutions for common issues.
  
  
  Contact SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance.
