• What is the cause and solution for SAP error message FSBP_TC007 - Error in RFC call; no free resources exist ?

  The SAP error message FSBP_TC007: Error in RFC call; no free resources exist typically indicates that the system is unable to allocate resources for a Remote Function Call (RFC). This can happen for several reasons, and understanding the cause is crucial for finding a solution.
  Causes:
  
  Resource Limitations: The SAP system may have reached its limit for concurrent RFC calls. This can happen if there are too many active sessions or if the system is under heavy load.
  Configuration Issues: The configuration settings for the RFC destination or the SAP Gateway may not be optimized, leading to resource allocation issues.
  Network Issues: Problems with the network can also lead to failures in establishing RFC connections.
  System Performance: If the SAP system is experiencing performance issues, it may not be able to handle additional RFC calls.
  Locks or Deadlocks: If there are locks or deadlocks in the system, it may prevent new RFC calls from being processed.
  
  Solutions:
  
  Check System Load: Monitor the system's performance and load. Use transaction codes like SM50 (to check active processes) and SM66 (to check global processes) to identify if there are too many active sessions.
  Increase RFC Resources: If the system is consistently hitting resource limits, consider increasing the number of allowed RFC connections. This can be done in the SAP profile parameters (e.g., rdisp/rfc_max_connections).
  Optimize Configuration: Review the configuration of the RFC destination and the SAP Gateway. Ensure that the settings are appropriate for your system's workload.
  Check for Locks: Use transaction SM12 to check for any locks that may be causing issues. If there are unnecessary locks, they can be released.
  Network Troubleshooting: Ensure that there are no network issues affecting the RFC calls. Check connectivity and performance between the systems involved in the RFC call.
  System Restart: In some cases, restarting the SAP application server may help clear up resource allocation issues.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM21 (System Log), ST22 (Dump Analysis), and SM37 (Job Monitoring) to gather more information about the system's state when the error occurs.
  SAP Basis Team: If you are not a Basis administrator, it may be necessary to involve your SAP Basis team to investigate and resolve the issue.
  Documentation: Review SAP documentation and community forums for additional insights and similar cases.
  
  By following these steps, you should be able to identify the cause of the FSBP_TC007 error and implement a suitable solution.
