• What is the cause and solution for SAP error message IUUC_MAIN109 - Shadow dictionary for table &1 RFC destination &2 does not exist ?

  The SAP error message IUUC_MAIN109 indicates that there is an issue with the shadow dictionary for a specific table in the context of the SAP Landscape Transformation (SLT) replication process. This error typically arises when the shadow dictionary for the specified table does not exist in the target system, which is required for the replication process to function correctly.
  Cause:
  
  Missing Shadow Dictionary: The shadow dictionary for the specified table has not been created in the target system.
  Incorrect RFC Destination: The RFC destination specified in the error message may be incorrect or not properly configured.
  Replication Setup Issues: There may be issues with the initial setup of the SLT replication configuration, leading to the shadow dictionary not being created.
  Transport Issues: If the table structure was recently changed or transported, the shadow dictionary may not have been updated accordingly.
  
  Solution:
  
  
  Check RFC Destination:
  
  Verify that the RFC destination specified in the error message is correctly configured and points to the correct target system.
  Use transaction SM59 to check the configuration of the RFC destination.
  
  
  
  Create Shadow Dictionary:
  
  If the shadow dictionary does not exist, you can create it manually. This can typically be done by reinitializing the replication for the specific table.
  Use transaction SLT to access the SLT configuration and reinitialize the table replication.
  
  
  
  Check Replication Configuration:
  
  Ensure that the table is included in the SLT configuration and that the replication settings are correct.
  If necessary, remove and re-add the table to the replication configuration.
  
  
  
  Monitor SLT Logs:
  
  Check the SLT logs for any additional error messages or warnings that may provide more context about the issue.
  Use transaction SLG1 to view the application logs related to SLT.
  
  
  
  Transport Changes:
  
  If the issue arose after a transport, ensure that all necessary objects related to the table and its shadow dictionary have been transported correctly.
