• What is the cause and solution for SAP error message WAB021 - Internal error: BAdI implementation for filter & missing ?

  SAP Error Message:
  
  WAB021 Internal error: BAdI implementation for filter & missing
  
  Cause
  This error occurs when the SAP system expects a Business Add-In (BAdI) implementation for a specific filter value, but no implementation is found or assigned. In other words, the system is trying to execute a BAdI with a particular filter criterion, but the corresponding implementation that matches this filter is missing.
  This typically happens in scenarios where:
  
  A BAdI is defined with filter-dependent implementations.
  The filter value used at runtime does not have an associated implementation.
  The BAdI implementation was not created or activated for the required filter value.
  The filter value passed is incorrect or not maintained.
  
  
  Explanation
  
  BAdI (Business Add-In): A SAP enhancement technique that allows custom code to be inserted into standard SAP programs.
  Filter-dependent BAdI: A BAdI that can have multiple implementations, each assigned to a specific filter value. At runtime, the system selects the implementation based on the filter value.
  If the system cannot find an implementation for the filter value used, it raises this internal error.
  
  
  Solution
  
  
  Check the BAdI Definition:
  
  Identify the BAdI involved in the error.
  Check if it is filter-dependent (i.e., has filter values defined).
  
  
  
  Verify Filter Values:
  
  Check which filter values are defined in the BAdI.
  Confirm the filter value passed at runtime.
  
  
  
  Create or Assign BAdI Implementation:
  
  If no implementation exists for the filter value, create a new implementation for that filter.
  Use transaction SE18 (BAdI Builder) or SE19 (BAdI Implementation) to create or maintain implementations.
  Assign the correct filter value to the implementation.
  
  
  
  Activate the Implementation:
  
  Ensure the implementation is active.
  
  
  
  Check Customizing or Configuration:
  
  Sometimes the filter value is derived from customizing or configuration.
  Verify that the configuration is correct and consistent with the BAdI filter values.
  
  
  
  Debugging:
  
  If unsure about the filter value passed, debug the program to see what filter value is used when calling the BAdI.
  This helps identify if the filter value is incorrect or unexpected.

  Summary
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Missing BAdI implementation for the filter value used at runtime.
  
  
  Effect
  System raises internal error WAB021.
  
  
  Solution
  Create and activate a BAdI implementation for the missing filter value.
  
  
  Tools
  SE18, SE19, debugging to identify filter values.
  
  
  Prevention
  Ensure all required filter values have corresponding active BAdI implementations.
  
  
  
  
  If you provide the specific BAdI name or context (e.g., module or transaction), I can help you with more targeted instructions.
