• What is the cause and solution for SAP error message ISLM_DI_GEN315 - For RFC, destination is mandatory. ?

  The SAP error message ISLM_DI_GEN315, which states "For RFC, destination is mandatory," typically occurs when there is an attempt to execute a Remote Function Call (RFC) without specifying a destination. This can happen in various scenarios, such as when trying to call a function module or when configuring a connection to an external system.
  Cause:
  
  Missing RFC Destination: The most common cause of this error is that the RFC destination has not been defined or is not being passed correctly in the function call.
  Configuration Issues: The RFC destination may not be configured properly in the SAP system.
  Authorization Issues: The user may not have the necessary authorizations to access the specified RFC destination.
  Incorrect Function Module Call: The function module being called may not be set up to handle the RFC call correctly.
  
  Solution:
  
  
  Define RFC Destination:
  
  Go to transaction code SM59 in the SAP GUI.
  Check if the required RFC destination is defined. If not, create a new RFC destination by clicking on "Create" and filling in the necessary details (e.g., target host, system number, client, user credentials).
  
  
  
  Check RFC Destination Configuration:
  
  Ensure that the RFC destination is configured correctly, including the connection type (e.g., TCP/IP) and the necessary parameters.
  Test the connection using the "Connection Test" button in SM59 to ensure it is working properly.
  
  
  
  Pass RFC Destination in Function Call:
  
  If you are calling a function module, ensure that you are passing the RFC destination correctly in your code. For example, if you are using a function module like RFC_PING, make sure to specify the destination.
  
  
  
  Check Authorizations:
  
  Verify that the user executing the RFC call has the necessary authorizations to access the RFC destination. This can be checked in transaction code SU01 for user roles and authorizations.
  
  
  
  Review Function Module:
  
  If you are using a custom function module, ensure that it is designed to handle RFC calls properly. Check the parameters and ensure that the destination is being handled as expected.
