• What is the cause and solution for SAP error message CNV_PE_GEN101 - DDIC structure for data model parameter &1 not available ?

  The SAP error message CNV_PE_GEN101 indicates that a Data Dictionary (DDIC) structure for a specific data model parameter is not available. This error typically arises during data migration or conversion processes, particularly when using SAP's tools for data migration, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  
  
  Missing DDIC Structure: The primary cause of this error is that the required Data Dictionary structure (DDIC) for the specified parameter is not defined in the system. This could be due to:
  
  The structure not being created or activated.
  The structure being deleted or not transported correctly to the system.
  A mismatch between the expected structure and the actual structure in the system.
  
  
  
  Incorrect Configuration: The configuration settings for the data model may not be set up correctly, leading to the system looking for a structure that does not exist.
  
  
  Version Mismatch: If you are using a version of the migration tool that is not compatible with your current SAP system version, it may lead to missing structures.
  
  
  Solution:
  
  
  Check DDIC Structures: 
  
  Use transaction SE11 to check if the required DDIC structure exists. If it does not exist, you may need to create it or transport it from another system.
  If the structure exists but is not activated, activate it.
  
  
  
  Review Migration Settings: 
  
  Ensure that the migration settings and parameters are correctly configured. Check the documentation for the specific migration tool you are using to ensure all prerequisites are met.
  
  
  
  Transport Issues: 
  
  If the structure is supposed to be in the system but is missing, check the transport logs to see if there were any issues during the transport process.
  
  
  
  Consult SAP Notes: 
  
  Search for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues.
