• What is the cause and solution for SAP error message CNV_10020678 - Input help is only available for value lists ?

  The SAP error message CNV_10020678: Input help is only available for value lists typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.

  Solution:
  
  Check Field Configuration: Verify the configuration of the field in the relevant data model or table. Ensure that it is linked to a domain or data element that has a value list defined.
  Define Value List: If the field is custom or does not have a predefined value list, consider creating a value list or domain for that field. This can be done through transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator).
  Use Alternative Input: If input help is not available, you may need to manually enter the valid values for the field based on the business requirements or data specifications.
  Consult Documentation: Review the SAP documentation or migration guides related to the specific migration scenario you are working on. There may be specific instructions or considerations for the fields involved.
