• What is the cause and solution for SAP error message /SAPPO/ACR109 - &1: RFC destination &2 has connection typ &3. It must be 3 or I ?

  The SAP error message /SAPPO/ACR109 &1: RFC destination &2 has connection type &3. It must be 3 or I indicates an issue with the configuration of an RFC (Remote Function Call) destination in your SAP system. This error typically arises when the connection type of the specified RFC destination is not set to the expected values, which are either "3" (for TCP/IP connections) or "I" (for HTTP connections).
  Cause:
  
  Incorrect RFC Destination Configuration: The RFC destination specified in the error message is configured with a connection type that is not supported for the operation you are trying to perform. The connection type could be set to "T" (Transactional RFC) or another type that is not compatible.
  System Configuration Issues: There may be a misconfiguration in the system settings or the RFC destination itself.
  
  Solution:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in your SAP system.
  Locate the RFC destination mentioned in the error message (replace &2 with the actual RFC destination name).
  Check the connection type field. It should be set to either "3" (TCP/IP) or "I" (HTTP).
  If it is set to a different value, change it to "3" or "I" as required.
  
  
  
  Test the RFC Connection:
  
  After making changes, use the "Test Connection" button in the SM59 transaction to ensure that the connection is working properly.
  
  
  
  Review Documentation: If you are unsure about the correct connection type to use, refer to the documentation for the specific SAP application or module you are working with, as it may provide guidance on the required RFC configuration.
  
  
  Consult Basis Team: If you do not have the necessary permissions to change the RFC destination settings, or if the issue persists after making changes, consult your SAP Basis team for further assistance.
