• What is the cause and solution for SAP error message 1BKKBAPI020 - Single-use BAdI &1 has multiple implementation classes; contact tech supp ?

  The SAP error message 1BKKBAPI020 indicates that there is a problem with a Business Add-In (BAdI) implementation in your SAP system. Specifically, it states that a single-use BAdI has multiple implementation classes, which is not allowed. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Multiple Implementations: The error occurs when there are multiple active implementations of a single-use BAdI. Single-use BAdIs are designed to allow only one implementation at a time, and having more than one leads to ambiguity in which implementation should be executed.
  Configuration Issues: There may be a configuration issue where the system is not correctly recognizing the active implementation.
  Transport Issues: If BAdI implementations were transported from one system to another (e.g., from development to production), it could lead to inconsistencies.
  
  Solution:
  
  
  Check Active Implementations:
  
  Go to the BAdI definition in the SAP system (transaction code SE18).
  Check the active implementations for the BAdI. You can do this by navigating to the "Implementations" tab.
  If you find multiple implementations, you will need to deactivate or delete the unnecessary ones.
  
  
  
  Deactivate Unused Implementations:
  
  If you have identified multiple implementations, you can deactivate the ones that are not needed. This can be done in the "Implementations" tab by selecting the implementation and choosing the option to deactivate it.
  
  
  
  Contact Technical Support:
  
  If you are unable to resolve the issue or if you are unsure about which implementation to keep, it is advisable to contact your technical support team or SAP support for assistance.
  
  
  
  Review Transport Requests:
  
  If the issue arose after a transport, review the transport requests to ensure that the correct implementations were moved and that there are no conflicts.
  
  
  
  Related Information:
  
  BAdI Definition: A Business Add-In (BAdI) is a way to enhance SAP applications without modifying the original code. Single-use BAdIs are meant to have only one implementation.
  Transaction Codes:
  
  SE18: To view BAdI definitions.
  SE19: To manage BAdI implementations.
  
  
  Documentation: Refer to SAP Help documentation for more details on BAdIs and their usage.
  
  Conclusion:
  Resolving the 1BKKBAPI020 error involves identifying and managing the active implementations of the BAdI in question. Ensure that only one implementation is active at any time for single-use BAdIs, and seek technical support if needed.
