GPZ (ABAP) - Not Enough Dialog Resources (GPZ asgpz00_GPZ_00 (ABAP_SRV))
Root cause: 
The ABAP instance had limited or no resources left for dialog processing, as indicated by the alert details showing 1 long-running dialog work process with a minimum runtime of 1200 seconds.  
 
Resolution steps: 
Checked the work process status using transaction SM50 to identify resource constraints. 
Analyzed user sessions with transaction SM04 to determine the impact of long-running processes on dialog resources. 
There are enough Dialog resources to process.
