• What is the cause and solution for SAP error message /ISDFPS/WKC045 - Implementation of BAdI methods is missing or exists more than once ?

  The SAP error message /ISDFPS/WKC045 indicates that there is an issue with the implementation of a Business Add-In (BAdI) method in the SAP system. Specifically, this error occurs when:
  
  
  Cause:
  
  The BAdI method has not been implemented at all, meaning that there is no active implementation for the method that the system is trying to call.
  Alternatively, there may be multiple implementations of the same BAdI method, which can lead to ambiguity about which implementation should be executed.
  
  
  
  Solution:
  
  Check Implementations: Go to transaction SE18 (BAdI Definition) and enter the name of the BAdI to check if there are any existing implementations. If there are no implementations, you will need to create one.
  Create Implementation: If no implementation exists, you can create one by using transaction SE19 (BAdI Implementation). Make sure to implement all required methods as per the BAdI definition.
  Remove Duplicate Implementations: If there are multiple implementations, you need to either deactivate or delete the unnecessary ones. You can do this in transaction SE19 by selecting the implementation and choosing to deactivate or delete it.
  Check Activation: Ensure that the implementation you want to use is activated. You can check this in the same transaction (SE19).
  
  
  
  Related Information:
  
  BAdI Documentation: Review the documentation for the specific BAdI to understand its purpose and the methods that need to be implemented.
