• What is the cause and solution for SAP error message CNV_PE579 - Local DDIC type information will be used ?

  The SAP error message CNV_PE579, which states "Local DDIC type information will be used," typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This message indicates that the system is unable to find the appropriate Data Dictionary (DDIC) type information in the target system and is defaulting to local DDIC type information instead.
  Cause:
  
  Missing or Incomplete DDIC Objects: The target system may not have the necessary Data Dictionary objects (like tables, structures, or data elements) defined, which are required for the migration process.
  Version Mismatch: There may be a version mismatch between the source and target systems, leading to discrepancies in the DDIC definitions.
  Transport Issues: If the required DDIC objects were not transported correctly to the target system, this could lead to the error.
  Custom Developments: If there are custom data types or structures that are not present in the target system, the system will revert to local definitions.
  
  Solution:
  
  Check DDIC Objects: Verify that all necessary Data Dictionary objects are present in the target system. You can do this by comparing the source and target systems or by checking the migration documentation.
  Transport Missing Objects: If you find that certain DDIC objects are missing, transport them from the source system to the target system.
  Update Target System: Ensure that the target system is updated to the same version as the source system, especially if you are migrating from an older version of SAP to S/4HANA.
  Review Custom Developments: If there are custom data types or structures, ensure that they are also defined in the target system.
  Consult SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on data migration issues.
