This typically occurs in the context of data replication or data transfer processes, where the system expects the key settings to be consistent across different sources.
  Cause:
  The inconsistency can arise due to several reasons:
  
  Configuration Issues: The key settings for the field in question may have been configured differently in the two systems or tables being compared.
  Data Model Changes: Changes in the data model (e.g., changes in the structure of tables or fields) that have not been synchronized across all relevant systems.
  Transport Issues: If changes were transported from one system to another, there may have been errors or omissions during the transport process.
  Custom Development: Custom developments or enhancements that modify the standard behavior of key fields may lead to inconsistencies.
