  Consult Documentation: 
  
  Review SAP documentation or consult with your SAP administrator for best practices regarding naming conventions and data types.
  
  
  
  Check for Transport Requests: 
  
  If you are working in a development environment, ensure that there are no pending transport requests that might affect the existing set.
