PFI (ABAP) - Not Enough Dialog Resources (PFI aspfi00_PFI_00 (ABAP_SRV))
Root cause: 
The ABAP instance had limited or no resources left for dialog processing, resulting in a 'Not Enough Dialog Resources' alert. This was indicated by the metric details showing 1 long-running dialog work process with a minimum runtime of 1200 and an elapsed time of 1390.  
 
Resolution steps: 
- Checked the work process status using transaction SM50 to identify resource constraints. there are about  18free dialog WP out of 25. 
- Analyzed user sessions with transaction SM04 to determine the impact of long-running processes. Users can login to this system.
