  Master Data Issues: Problems with master data (like customer or material master records) can lead to inconsistencies in the pricing conditions.
  
  
  Customizations or Enhancements: If there are custom developments or enhancements in the pricing logic, they may not be handling certain condition types correctly.
  
  
  Transport Issues: If the configuration or condition records were transported from one system to another (e.g., from development to production), there may have been issues during the transport process.
