• What is the cause and solution for SAP error message WS601 - Message type &1 does not support transmission medium &2 ?

  The SAP error message:
  WS601 Message type &1 does not support transmission medium &2
  
  Cause:
  This error occurs when you try to send a message of a certain message type using a transmission medium that is not supported or not configured for that message type in the SAP system.
  In SAP, each message type (e.g., ORDERS, INVOIC, etc.) is configured to be sent via specific transmission media (e.g., EDI, IDoc, print, email). If you attempt to send a message using a medium that is not assigned or allowed for that message type, the system raises this error.
  
  Explanation:
  
  Message type (&1): The type of message you are trying to send (e.g., ORDERS).
  Transmission medium (&2): The medium you are trying to use to send the message (e.g., EDI, print, email).
  
  The system checks the configuration in the partner profile or message control settings and finds that the message type does not support the specified transmission medium.
  
  Solution:
  
  
  Check the partner profile (WE20):  
  
  Go to transaction WE20.
  Select the relevant partner.
  Check the outbound parameters for the message type in question.
  Verify if the transmission medium you want to use is assigned to the message type.
  If not, assign the correct transmission medium (e.g., EDI, print, etc.) to the message type.
  
  
  
  Check message control configuration (NACE):  
  
  Go to transaction NACE.
  Select the application (e.g., V1 for sales orders).
  Check the output types and their assigned transmission media.
  Ensure that the output type related to your message type supports the transmission medium you want to use.
  
  
  
  Adjust the output determination procedure:  
  
  Make sure the output type determination procedure is correctly set up to allow the transmission medium.
  
  
  
  If using IDocs:  
  
  Check the partner profile for the outbound parameters.
  Ensure the message type is assigned to the correct port and that the port supports the transmission medium.
  
  
  
  If the transmission medium is not supported at all:  
  
  You may need to configure or develop support for that medium or choose a supported medium.

  Summary:
  The error WS601 indicates a mismatch between the message type and the transmission medium. Correcting the configuration in partner profiles or output determination to align the message type with a supported transmission medium resolves the issue.
