• What is the cause and solution for SAP error message /SCWM/MFS099 - Host and port combination used for entry &1; combination must be unique ?

  The SAP error message /SCWM/MFS099 indicates that there is a conflict with the host and port combination used for a specific entry in the system. This error typically arises in the context of the SAP Extended Warehouse Management (EWM) and its integration with the Material Flow System (MFS).
  Cause:
  The error occurs when you attempt to create or configure a new entry (such as a communication channel or a connection) in the system that uses a host and port combination that is already in use by another entry. In other words, the system requires that each host and port combination be unique to avoid conflicts in communication.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Entries:
  
  Go to the relevant configuration area in SAP where host and port combinations are defined (e.g., in the MFS settings).
  Look for existing entries that use the same host and port combination as the one you are trying to create.
  
  
  
  Modify or Delete Conflicting Entry:
  
  If you find an existing entry with the same host and port, you can either modify it (if applicable) or delete it if it is no longer needed.
  Ensure that the new entry you are trying to create has a unique combination of host and port.
  
  
  
  Create a Unique Combination:
  
  If you need to keep the existing entry, consider using a different port number or host name for the new entry you are trying to create.
  
  
  
  Check for Typographical Errors:
  
  Ensure that there are no typographical errors in the host or port values you are entering.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on configuring MFS and EWM settings.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs.
