How To Fix ENHANCEMENT479 - BAdI implementation w/o enhancement implementation only in classic BAdIs

SAP Error Message - Details

• Message type: E = Error

• Message class: ENHANCEMENT - SAP customer enhancement project messages

• Message number: 479

• Message text: BAdI implementation w/o enhancement implementation only in classic BAdIs

What causes this issue?

BAdI implementations can be created either as classic BAdIs or as new
ones integrated in the ABAP language.
The implementation of a classic BAdI is identified uniquely by its BAdI
implementation name of 20 characters. The enhancement implementation
name must be empty.
Implementing the ABAP-based BAdI is part of an enhancement
implementation. For unique identification, the enhancement
implementation and the BAdI implementation are required.

System Response

Since the enhancement implementation name is empty, the checkbox
'Classic BAdI Implementation' is marked.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message ENHANCEMENT479 - BAdI implementation w/o enhancement implementation only in classic BAdIs ?

  The SAP error message ENHANCEMENT479 typically occurs when you are trying to implement a Business Add-In (BAdI) in a classic BAdI context without having the necessary enhancement implementation in place. This error is specifically related to the classic BAdI framework, which is different from the newer BAdI implementations that use the new enhancement framework.
  Cause:
  The error arises when:
  
  You attempt to implement a classic BAdI without having a corresponding enhancement implementation.
  The system expects an enhancement implementation to be defined for the BAdI, but it is missing.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check BAdI Definition: 
  
  Go to transaction SE18 and enter the BAdI name that is causing the error. Check the definition and see if it is a classic BAdI.
  
  
  
  Create Enhancement Implementation:
  
  If the BAdI is indeed a classic BAdI, you need to create an enhancement implementation for it.
  Go to transaction SE19 (BAdI Implementation) and create a new implementation for the BAdI.
  Ensure that you provide a valid implementation name and description.
  
  
  
  Activate the Implementation:
  
  After creating the implementation, make sure to activate it. This is crucial as the system will not recognize the implementation until it is activated.
  
  
  
  Check for Conflicts:
  
  Ensure that there are no conflicting implementations for the same BAdI. If there are multiple implementations, the system may not know which one to use.
  
  
  
  Review Documentation:
  
  Check the SAP documentation or notes related to the specific BAdI for any additional requirements or steps that may be necessary.
  
  
  
  Related Information:
  
  Classic BAdIs vs. New BAdIs: Classic BAdIs are defined in a different way compared to the newer BAdI implementations. The newer BAdIs allow for multiple implementations without the need for a specific enhancement implementation.
  Transaction Codes:
  
  SE18: To view BAdI definitions.
  SE19: To create and manage BAdI implementations.
  
  
  SAP Notes: Always check for relevant SAP Notes that may provide additional insights or solutions related to specific BAdI implementations.
  
  By following these steps, you should be able to resolve the ENHANCEMENT479 error and successfully implement the BAdI.
