ENHANCEMENT173 - Details

• The SAP error message "ENHANCEMENT173 Function code & already exists in BAdI definition &" typically occurs when you are trying to create or implement a Business Add-In (BAdI) and the function code you are attempting to use is already defined in the BAdI definition. This can happen during the implementation of enhancements in SAP systems, particularly when working with BAdIs that allow for custom functionality.
  
  Cause:
  
  Duplicate Function Code: The function code you are trying to implement is already defined in the BAdI. Each BAdI can have multiple implementations, but each implementation must have a unique function code.
