• What is the cause and solution for SAP error message RT196 - Transactional RFC: Logical units of work waiting to be executed ?

  The SAP error message RT196 indicates that there are logical units of work (LUWs) in a Transactional RFC (tRFC) that are waiting to be executed. This situation typically arises when there are issues with the communication between systems or when the system is unable to process the queued requests for some reason.
  Causes:
  
  Network Issues: Problems with the network connection between the systems can prevent the tRFC calls from being executed.
  System Performance: If the system is under heavy load or experiencing performance issues, it may not be able to process the queued LUWs in a timely manner.
  Configuration Issues: Incorrect configuration of the tRFC settings or the RFC destination can lead to issues in processing.
  Database Locks: If there are locks on the database that prevent the execution of the tRFC calls, this can cause LUWs to wait.
  Error in the Called Function Module: If the function module being called has errors or is not available, it can lead to LUWs being stuck.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the systems involved in the tRFC communication.
  Monitor System Performance: Use transaction codes like ST03N or ST22 to monitor system performance and check for any performance bottlenecks.
  Review tRFC Configuration: Verify the configuration of the tRFC settings and the RFC destination using transaction code SM59. Ensure that the destination is correctly configured and reachable.
  Check for Database Locks: Use transaction code SM12 to check for any locks on the database that might be preventing the execution of LUWs.
  Analyze Error Logs: Use transaction codes SLG1 (Application Log) and SM21 (System Log) to check for any error messages that might provide more context on why the LUWs are waiting.
  Reprocess LUWs: If the issue has been resolved, you can reprocess the waiting LUWs using transaction code SM58. This transaction allows you to monitor and manage tRFC calls.
