This error typically occurs during the design phase of a data model or when modifying existing data structures in SAP.
  Cause:
  The error is caused by:
  
  Duplicate Field Definition: You are trying to add a field with a name that already exists in the specified object (e.g., a table or structure).
  Incorrect Naming: The field name you are trying to use may have been previously defined, either in the same object or in a related object.

  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Existing Fields: Review the existing fields in the specified object (e.g., table or structure) to confirm if the field name you are trying to use is already defined.
  
  Use transaction codes like SE11 (Data Dictionary) to view the structure or table definitions.
  
  
  
  Rename the Field: If the field name is indeed already in use, consider renaming the new field to a unique name that does not conflict with existing definitions.
  
  
  Modify Existing Field: If the intention was to modify an existing field, ensure that you are making changes to the correct field rather than trying to create a new one.
  
  
  Check for Dependencies: If the field is part of a larger data model or is referenced in other objects, ensure that any changes you make do not break existing dependencies.
  
  
  Consult Documentation: If you are unsure about the naming conventions or the structure of the data model, refer to the relevant SAP documentation or guidelines.
  
  
  Collaboration: If you are working in a team, communicate with your colleagues to ensure that there are no overlapping definitions.
