• What is the cause and solution for SAP error message RSSDK017 - First select a functional RFC destination ?

  The SAP error message RSSDK017 ("First select a functional RFC destination") typically occurs when you are trying to execute a function module or a remote-enabled function module (RFC) without having specified a valid RFC destination. This error is common in scenarios where you are working with remote function calls in SAP.
  Cause:
  The error is caused by the absence of a selected functional RFC destination in the context of the operation you are trying to perform. A functional RFC destination is required to establish a connection to another SAP system or an external system to execute the desired function.
  Solution:
  To resolve the RSSDK017 error, follow these steps:
  
  
  Select a Functional RFC Destination:
  
  Go to the transaction code where you are encountering the error (e.g., SE37 for function modules).
  Before executing the function module, ensure that you have selected a valid functional RFC destination.
  You can do this by navigating to the "RFC Destination" field and selecting an appropriate destination from the dropdown list.
  
  
  
  Check RFC Destination Configuration:
  
  Use transaction code SM59 to check the configuration of the RFC destination.
  Ensure that the destination is correctly configured and that it points to the correct target system.
  Test the connection to ensure that it is working properly.
  
  
  
  Review Authorization:
  
  Ensure that the user executing the function has the necessary authorizations to access the selected RFC destination.
  
  
  
  Check Function Module Settings:
  
  If you are developing or modifying a function module, ensure that it is marked as remote-enabled if it is intended to be called remotely.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the program or function module to identify where the RFC destination is being set or not set.
  
  
  
  Related Information:
