• What is the cause and solution for SAP error message VSCAN088 - Blacklist indicator is only meaningful with an active MIME check ?

  The SAP error message VSCAN088 indicates that the blacklist indicator is only relevant when a MIME (Multipurpose Internet Mail Extensions) check is active. This error typically arises in the context of SAP's virus scanning and security measures, particularly when dealing with file uploads or downloads.
  Cause:
  The error occurs when:
  
  The system is configured to use a blacklist for file types or MIME types, but the MIME check itself is not enabled.
  The blacklist feature is intended to prevent the upload of certain file types that are deemed unsafe, but without the MIME check being active, the blacklist has no effect.
  
  Solution:
  To resolve this error, you need to ensure that the MIME check is enabled in your SAP system. Here are the steps to do this:
  
  Access the SAP GUI: Log in to your SAP system.
  Navigate to the Transaction Code: Use transaction code RZ10 to access the profile parameters.
  Check the Parameters: Look for the parameter icm/HTTP/verify_mime and ensure it is set to 1 (enabled).
  Modify the Profile: If it is not enabled, you can change it to 1 and save the changes.
  Restart the ICM: After making changes to the profile parameters, you will need to restart the Internet Communication Manager (ICM) for the changes to take effect. This can typically be done through transaction SMICM.
  Verify Configuration: After restarting, verify that the MIME check is now active and that the blacklist indicator can be used effectively.
