This article answers the following queries :
- How to avoid TIME_OUT dumps in SAP system ?
- There are lot of TIME_OUT dumps in ST22 transaction. How to avoid these dumps ?
---------------------------------------------------------------------------------------------
These TIME_OUT dumps usually occur if the program has exceeded the maximum permitted runtime without interruption. After this program will get terminated and in ST22 a dump will get generated.
Usually SAP system will terminate the program after permitted runtime to make the work area available to other users who may waiting and to prevent a work area being blocked unnecessarily long time like
Eg: Database accesses without a suitable index (Full table scan)
Database access with a large result set
Endless loops (DO, WHILE) etc
In SAP, there is a parameter rdisp/max_wprun_time which limits the maximum permitted runtime without interruption. By default this value is set to 600 seconds. However, if you are frequently encountering more dumps in SAP system due to this, you can consider increasing this value to 3600 seconds to avoid this issue.
