• What is the cause and solution for SAP error message CRM_MKTHV_SMM010 - No free RFC destinations available ?

  The SAP error message CRM_MKTHV_SMM010: No free RFC destinations available typically indicates that the system is unable to establish a Remote Function Call (RFC) connection to another system or service because there are no available RFC destinations. This can occur in various scenarios, such as when trying to access external systems or services from within the SAP CRM environment.
  Causes:
  
  Exhausted RFC Connections: The maximum number of allowed RFC connections has been reached. This can happen if there are too many active connections or if connections are not being released properly.
  Configuration Issues: The RFC destination may not be configured correctly, or the destination may not be available.
  Network Issues: There may be network connectivity issues preventing the system from reaching the RFC destination.
  System Resource Limitations: The SAP system may be running low on resources (e.g., memory, CPU), which can affect its ability to handle RFC connections.
  Authorization Issues: The user or system may not have the necessary authorizations to establish an RFC connection.
  
  Solutions:
  
  
  Check Active Connections:
  
  Use transaction SM04 to check for active user sessions and connections. If there are many active sessions, consider terminating unnecessary ones.
  Use transaction SMGW to monitor the gateway and check for any stuck or inactive connections.
  
  
  
  Increase RFC Connection Limits:
  
  You can increase the number of allowed RFC connections by adjusting the parameters in the SAP system. This can be done in transaction RZ10 by modifying the instance profile parameters such as rfc/max_connections.
  
  
  
  Review RFC Destination Configuration:
  
  Check the configuration of the RFC destination in transaction SM59. Ensure that the destination is correctly set up and that the connection type is appropriate.
  Test the RFC connection from SM59 to ensure it is working properly.
  
  
  
  Check System Resources:
  
  Monitor system resources using transaction ST02 (buffer management) and ST06 (OS-level monitoring) to ensure that the system is not under heavy load.
  
  
  
  Network Troubleshooting:
  
  Verify network connectivity to the target system. Use tools like ping or traceroute to check connectivity.
  Ensure that firewalls or network policies are not blocking the RFC connections.
  
  
  
  Review Authorizations:
  
  Ensure that the user or service account being used to establish the RFC connection has the necessary authorizations.
