• What is the cause and solution for SAP error message RZ795 - Maximum number (32) of external RFC logon groups reached ?

  The SAP error message RZ795: Maximum number (32) of external RFC logon groups reached indicates that the system has reached the maximum limit of external RFC (Remote Function Call) logon groups that can be defined. This typically occurs when there are too many external systems trying to connect to the SAP system using RFC connections.
  Cause:
  
  Exceeding Limit: The SAP system has a predefined limit of 32 external RFC logon groups. If you attempt to create more than this number, you will encounter this error.
  Configuration Issues: There may be misconfigurations in the RFC destinations or logon groups that lead to the system trying to create additional logon groups unnecessarily.
  Legacy Connections: Old or unused connections that are still defined in the system may be consuming the available logon groups.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Review Existing Logon Groups:
  
  Go to transaction SM59 (RFC Destinations) and check the existing external RFC logon groups.
  Identify any unused or obsolete logon groups that can be deleted.
  
  
  
  Delete Unused Logon Groups:
  
  If you find any logon groups that are no longer needed, delete them to free up space for new connections.
  
  
  
  Consolidate Connections:
  
  If possible, consolidate multiple RFC connections into fewer logon groups. This can help manage the number of logon groups more effectively.
  
  
  
  Check Configuration:
  
  Review the configuration of your RFC destinations to ensure that they are set up correctly and that there are no unnecessary connections being created.
  
  
  
  Increase the Limit (if applicable):
  
  In some cases, it may be possible to increase the limit of external RFC logon groups by adjusting system parameters. However, this is generally not recommended unless absolutely necessary, as it may have implications on system performance and stability.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional guidance or solutions specific to your version of SAP.
