• What is the cause and solution for SAP error message RT200 - Transactional RFC: Number of old calls ?

  The SAP error message RT200, which pertains to "Transactional RFC: Number of old calls," typically indicates that there are too many old or inactive calls in the Transactional Remote Function Call (tRFC) queue. This can happen when there are issues with the processing of tRFC calls, leading to a backlog of calls that have not been completed or acknowledged.
  Cause:
  
  Network Issues: Problems with network connectivity can prevent tRFC calls from being processed.

  Solution:
  
  Check tRFC Queue: Use transaction code SM58 to monitor the tRFC queue. Look for any calls that are stuck or have errors.
  Analyze Errors: Investigate the specific errors associated with the tRFC calls. This may involve checking logs or using transaction codes like SLG1 for application logs.
  Clear Old Calls: If there are old calls that are no longer needed, you can delete them from the tRFC queue using transaction SM58.
  Increase System Resources: If the system is under heavy load, consider increasing the resources (CPU, memory) available to the SAP system.
  Check Network Connectivity: Ensure that there are no network issues affecting the communication between systems.
  Review Configuration: Verify the configuration of the RFC destinations and ensure they are set up correctly.
