• What is the cause and solution for SAP error message CNV10994120 - No conversion-relevant data found in CDHDR and CDPOS => long text ?

  The SAP error message CNV10994120 indicates that there is no conversion-relevant data found in the change document tables CDHDR (Change Document Header) and CDPOS (Change Document Items). This error typically arises during data migration or conversion processes, particularly when using SAP's Data Migration tools or during system upgrades.
  Cause:
  
  
  No Change Documents: The primary cause of this error is that there are no change documents recorded in the CDHDR and CDPOS tables for the objects you are trying to convert or migrate. This can happen if:
  
  The relevant change documents were not created due to system settings.
  The data you are trying to convert has not been changed after the change document logging was activated.
  The change document logging is not enabled for the specific objects or tables you are working with.
  
  
  
  Incorrect Configuration: If the configuration for change document logging is not set up correctly, it may lead to the absence of relevant data in the change document tables.
  
  
  Data Selection Criteria: The selection criteria used during the migration process may not match any existing records in the change document tables.
  
  
  Solution:
  
  
  Check Change Document Logging:
  
  Ensure that change document logging is enabled for the relevant tables and objects. You can check this in the Data Dictionary (SE11) by looking at the table properties.
  If it is not enabled, you may need to activate it and ensure that changes are logged going forward.
  
  
  
  Verify Data:
  
  Check if there are any records in the CDHDR and CDPOS tables for the objects you are trying to convert. You can do this by executing a simple SQL query or using transaction codes SE16 or SE11.
  If there are no records, you may need to perform some changes to the data to generate change documents.
  
  
  
  Adjust Migration Parameters:
  
  Review the parameters or selection criteria used in your migration process. Ensure that they are correctly set to capture the relevant change documents.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific instructions or prerequisites that need to be followed.
