• What is the cause and solution for SAP error message CNV_PE_UI171 - Generated DDIC structure is not available ?

  The SAP error message CNV_PE_UI171: Generated DDIC structure is not available typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that a Data Dictionary (DDIC) structure that is expected to be generated or utilized is not available in the system.
  Causes:
  
  Missing DDIC Structure: The required DDIC structure has not been generated or is missing from the system.
  Incorrect Configuration: The configuration settings for the data migration process may be incorrect, leading to the system not being able to find the necessary structures.
  Transport Issues: If the DDIC structure was supposed to be transported from another system (e.g., development to production), there may have been issues with the transport.
  Version Compatibility: The version of the migration tool or the source system may not be compatible with the target system, leading to missing structures.
  Authorization Issues: The user executing the migration may not have the necessary authorizations to access the DDIC structures.
  
  Solutions:
  
  Check DDIC Structures: Verify if the required DDIC structure exists in the system. You can do this by using transaction SE11 (Data Dictionary) to check for the specific structure.
  Generate Missing Structures: If the structure is missing, you may need to regenerate it. This can often be done by executing the relevant migration program or transaction that is supposed to create the DDIC structure.
  Review Migration Configuration: Ensure that the configuration settings for the migration process are correct. Check if all necessary parameters are set properly.
  Transport Requests: If the structure was supposed to be transported, check the transport logs for any errors and ensure that the transport request has been successfully imported.
