• What is the cause and solution for SAP error message SWF_FLEX_RUN051 - RFC Destination '&1' has wrong type (Type: '&2') ?

  The SAP error message SWF_FLEX_RUN051 indicates that there is an issue with the RFC (Remote Function Call) destination configuration in your SAP system. Specifically, the error states that the RFC destination has the wrong type, which can lead to problems when trying to execute workflows or remote function calls.
  Cause:
  The error typically arises due to one of the following reasons:

  Misconfiguration: The RFC destination may not be set up correctly in the SAP system, leading to type mismatches.
  
  
  Network Issues: Sometimes, network issues or connectivity problems can lead to incorrect type recognition.
