• What is the cause and solution for SAP error message WES_OUTBOUND035 - The implementing class is not required at filter &1 and is ignored ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WES_OUTBOUND035
  
  Text: The implementing class is not required at filter &1 and is ignored.
  
  Cause:
  This warning message occurs in the context of SAP PI/PO (Process Integration / Process Orchestration) or SAP middleware when configuring outbound processing with filters and implementing classes.
  
  The message indicates that an implementing class has been assigned or specified for a particular filter in the outbound processing configuration.
  However, for the filter type or scenario in question, the implementing class is not required or not applicable.
  Therefore, the system ignores the implementing class setting for that filter.
  
  In other words, the configuration contains an implementing class where it is not needed or supported.
  
  When does this happen?
  
  When you configure an outbound processing step (e.g., in the Integration Directory or ESR) and assign an implementing class to a filter that does not support or require it.
  For example, certain filters or adapter modules expect no implementing class, or the implementing class is only relevant for inbound processing.
  This can also happen if the filter type is generic or does not invoke custom code.
  
  
  Solution:
  
  
  Review the filter configuration:
  
  Check the filter &1 (the filter name or ID is given in the message) in your outbound processing scenario.
  Verify if the implementing class is necessary or supported for this filter.
  
  
  
  Remove the implementing class if not needed:
  
  If the filter does not require an implementing class, remove it from the configuration.
  This will prevent the warning and clarify the configuration.
  
  
  
  Check documentation or SAP notes:
  
  Refer to SAP documentation for the specific adapter or scenario to understand when implementing classes are required.
  Sometimes, the implementing class is only valid for inbound filters or specific adapter modules.
  
  
  
  Test the scenario:
  
  After removing or correcting the implementing class assignment, test the outbound processing to ensure it works as expected.
  
  
  
  
  Related Information:
  
  This message is a warning, not an error, so it does not stop processing but indicates a potential misconfiguration.
  Implementing classes are typically used to add custom logic or enhancements in processing steps.
  Filters are used to select or route messages based on criteria; not all filters support custom implementing classes.
  Check SAP Notes or the SAP Community for similar issues if you suspect a bug or need further clarification.
