  Solution:
  
  Check Field Definitions: Review the BOL structure definition to identify where the duplicate field name is being used. You can do this by navigating to the relevant BOL configuration in the SAP system.
  Rename Fields: If you find that a field name is duplicated, consider renaming one of the fields to ensure that each field name is unique within the structure.
  Review Customizations: If you are working with custom BOL structures, ensure that your custom fields do not conflict with existing fields. Use unique prefixes or suffixes to differentiate custom fields.
  Use Transaction Codes: Utilize transaction codes like BOL or BOL_MAINTAIN to manage and maintain BOL structures effectively.
  Check for Inheritance: If your BOL structure inherits from another structure, ensure that the parent structure does not have a field with the same name.
