• What is the cause and solution for SAP error message EPD105 - No RFC connection to the CRM System has been maintained ?

  The SAP error message EPD105 indicates that there is no Remote Function Call (RFC) connection established to the CRM system. This error typically arises when trying to execute a function that requires communication between different SAP systems, such as between an ERP system and a CRM system.
  Cause:
  
  Missing RFC Connection: The RFC connection to the CRM system has not been created or is not properly configured.
  Incorrect Configuration: The existing RFC connection may be incorrectly configured, leading to connection failures.
  Network Issues: There may be network issues preventing the systems from communicating.
  Authorization Issues: The user may not have the necessary authorizations to access the RFC connection.
  System Downtime: The CRM system may be down or not reachable at the moment.
  
  Solution:
  
  
  Create or Maintain RFC Connection:
  
  Go to transaction SM59 in the SAP GUI.
  Check if the RFC connection to the CRM system exists. If it does not, create a new RFC connection.
  If it exists, ensure that it is correctly configured (check the connection parameters, target host, and service).
  Test the connection using the "Test Connection" button to ensure it is working properly.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no network issues preventing the two systems from communicating. You can use tools like ping or traceroute to check connectivity.
  
  
  
  Review Authorizations:
  
  Ensure that the user executing the function has the necessary authorizations to use the RFC connection.
  
  
  
  Check CRM System Status:
  
  Verify that the CRM system is up and running. If it is down, you will need to wait until it is back online.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) for any additional error messages that might provide more context about the issue.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support notes related to RFC connections for any specific configurations or troubleshooting steps.
  
  
  
  Related Information:
