This error indicates that a field is defined multiple times within the same context, which is not allowed.
  Cause:
  
  Duplicate Field Definitions: The most common cause of this error is that the same field has been defined more than once in a structure, table, or view.
  Inconsistent Data Model: If you are working with a data model that has been modified or updated, it is possible that the same field was inadvertently added multiple times.
  Incorrect Join Conditions: In the case of database views, if you are joining tables and the same field exists in both tables without proper aliasing, it can lead to this error.
  
  Solution:
  
  Check Field Definitions: Review the structure, table, or view definition where the error occurs. Look for duplicate field names and remove or rename the duplicates.
  Use Aliases: If you are working with database views and need to include fields from multiple tables that have the same name, use aliases to differentiate them.
  Modify Data Model: If the error arises from a data model change, ensure that the model is consistent and that fields are not duplicated across different objects.
  Recompile Objects: After making changes, recompile the affected objects to ensure that the changes take effect.
