• What is the cause and solution for SAP error message CNV_CMIS_A_20_FUNC040 - Comparison stopped: no DDIC information found for target system ?

  The SAP error message CNV_CMIS_A_20_FUNC040 indicates that the comparison process has been halted because the system could not find the Data Dictionary (DDIC) information for the target system. This error typically arises during data migration or system conversion processes, particularly when using SAP's Conversion and Migration tools.
  Cause:
  
  
  Missing DDIC Information: The target system does not have the necessary Data Dictionary information available. This could be due to:
  
  The target system not being properly set up or configured.
  The required transport requests not being imported into the target system.
  The target system being in a state where it cannot access the DDIC (e.g., if it is not fully operational).
  
  
  
  Incorrect Configuration: The configuration settings for the source and target systems may not be correctly defined, leading to the inability to retrieve the necessary DDIC information.
  
  
  Version Mismatch: There may be a version mismatch between the source and target systems, which can lead to incompatibilities in the DDIC structures.
  
  
  Solution:
  
  
  Check Target System Configuration:
  
  Ensure that the target system is correctly configured and operational.
  Verify that the necessary transport requests containing the DDIC objects have been imported into the target system.
  
  
  
  Verify DDIC Availability:
  
  Check if the Data Dictionary objects are available in the target system. You can do this by using transaction codes like SE11 (Data Dictionary) to see if the required tables, structures, or data elements exist.
  
  
  
  Review Migration Settings:
  
  Go through the migration settings and ensure that the source and target systems are correctly defined in the migration tool.
  Make sure that the connection between the source and target systems is properly established.
  
  
  
  Check for Version Compatibility:
  
  Ensure that both the source and target systems are compatible in terms of SAP version and support packages. If there are discrepancies, consider upgrading or aligning the systems.
  
  
  
  Consult SAP Notes:
  
  Look for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues.
  
  
  
  Log Analysis:
  
  Analyze the logs generated during the migration process for any additional error messages or warnings that could provide more context about the issue.
  
  
  
  Related Information:
