• Message number: 406

• Message text: Multiple implementations active for BAdI &1

What causes this issue?

The Business Add-In (BAdI) &V1& has been defined as a single-use BAdI,
but there are several active BAdI implementations, which are
simultaneously called in your system client.

System Response

Processing of the transaction stops.

How to fix this error?

Ask the system administrator to check the BAdI implementations in
transaction SE19.
The system should only call one BAdI implementation for the BAdI
definition &V1&.

Procedure for System Administrators

Errors in the BAdI framework should be reported to the OSS component
BC-DWB-CEX-BAD.

• What is the cause and solution for SAP error message BUBAS406 - Multiple implementations active for BAdI &1 ?

  The SAP error message BUBAS406 indicates that there are multiple active implementations of a Business Add-In (BAdI) for a specific BAdI definition. This situation can lead to ambiguity in which implementation should be executed, resulting in the error.
  Cause:
  The error occurs when:
  
  There are multiple active implementations of the same BAdI.
  The system cannot determine which implementation to use when the BAdI is called.
  
  Solution:
  To resolve this error, you need to ensure that only one implementation of the BAdI is active at a time. Here are the steps to do this:
  
  
  Identify Active Implementations:
  
  Go to transaction code SE18 (BAdI Definition) and enter the name of the BAdI that is causing the error.
  Click on the "Implementations" button to see all active implementations.
  
  
  
  Deactivate or Delete Unnecessary Implementations:
  
  Review the list of active implementations.
  If you find multiple implementations that are not needed, you can deactivate or delete the ones that are not required.
  To deactivate an implementation, go to transaction code SE19 (BAdI Implementation), select the implementation, and choose the option to deactivate it.
  
  
  
  Test the Changes:
  
  After deactivating the unnecessary implementations, test the functionality that was causing the error to ensure that it now works correctly.
  
  
  
  Documentation:
  
  Document the changes made for future reference and to inform other team members about the active implementations.
  
  
  
  Related Information:
  
  BAdI (Business Add-In): A BAdI is a type of enhancement in SAP that allows developers to add custom functionality to standard SAP applications without modifying the original code.
  Transaction Codes:
  
  SE18: To view BAdI definitions.
  SE19: To manage BAdI implementations.
  
  
  BAdI Implementation: Each BAdI can have multiple implementations, but only one can be active at a time unless it is defined as a multiple-use BAdI.
  
  By following these steps, you should be able to resolve the BUBAS406 error and ensure that your BAdI implementations are correctly configured.
