  The SAP error message /IWXBE/CORE059 indicates that there is an attempt to create a topic filter that already exists for a specific channel in the SAP system. This typically occurs in the context of SAP's Integration Suite or related messaging services where topic filters are used to manage message subscriptions.
  Cause:
  The error is triggered when:
  
  You are trying to create a new topic filter for a channel that already has a filter with the same name.

  Solution:

  Modify or Remove Duplicate:
  
  If the filter already exists and is valid, consider modifying your request to use the existing filter instead of trying to create a new one.

  Review Configuration:
  
  Check the configuration settings for the channel to ensure that there are no unintended duplicates being created.
  Ensure that your application logic does not attempt to create the same filter multiple times.
  
  
  
  Consult Documentation:
