• What is the cause and solution for SAP error message SRAL130 - bgRFC Unit ID &1 not found in RAL cache ?

  The SAP error message SRAL130 indicates that a background RFC (bgRFC) unit ID specified in the system is not found in the RAL (Reliable Asynchronous Layer) cache. This can occur in scenarios where the bgRFC framework is used for asynchronous communication between different SAP systems or within the same system.
  Cause:
  
  Unit ID Not Registered: The bgRFC unit ID may not have been registered properly in the RAL cache. This can happen if the unit was never created or if it was deleted or expired.
  Cache Issues: There may be issues with the RAL cache itself, such as corruption or misconfiguration.
  System Configuration: The system may not be configured correctly for bgRFC processing, leading to issues in finding the unit ID.
  Network Issues: If the bgRFC is supposed to communicate with another system, network issues could prevent the unit from being recognized.
  
  Solution:
  
  Check Unit ID: Verify that the bgRFC unit ID you are trying to access is correct and exists in the system. You can do this by checking the bgRFC monitor (transaction code SLG1 or SM58).
  Recreate Unit ID: If the unit ID is missing, you may need to recreate it. This can involve re-triggering the process that generates the bgRFC unit.
  Clear Cache: If you suspect cache corruption, you can try clearing the RAL cache. This can be done using transaction SLG1 to check logs and SM21 for system logs.
  Check Configuration: Ensure that the bgRFC configuration is correct. This includes checking the settings in transaction SM59 for RFC destinations and ensuring that the bgRFC settings are properly configured in the system.
  Monitor Background Jobs: Check if there are any background jobs that are failing or causing issues with bgRFC processing. Use transaction SM37 to monitor job statuses.
  System Restart: In some cases, a system restart may help in refreshing the cache and resolving transient issues.
