Re: Rebuilt a process in change module, now submit action errors out

they can be done whenever you require them, it's just recommended to do an IIS reset if you see any issues arise from the modification.

I would turn on logging for calculations in order to get a better idea of what's happeneing.  Odds are there is a NULL value being passed somewhere and the calculation cannot render a result because of that.

Enabling Calculation logging on Service Desk 7.5 onwards

1. Log in to Configuration Centre and find the Framework or Web Access application you want to enable the logging on.
2. Select the Diagnostics action.
3. Locate the Calculation category and set its logging level to All.
4. Press OK to save the change.

Enabling Calculation logging on Service Desk 7.4 or earlier

1. Connect to your Service Desk server.
2. Locate the tps.config file for your Framework of Web Access application you want to enable the logging on.  This is found under C:\ProgramData\Touchpaper\<application-name> on Windows Server 2008 and C:\Documents and Settings\All Users\Application Data\Touchpaper\<application-name> on Windows Server 2003.
3. Add the following line to the <appSettings> section: <add key="TraceLevel_Calculation" value="All" />.
4. Save the file.

Logging is now enabled and you will find the log files on the server in the LogFiles sub-folder below your tps.config file.

You may want to alter the trace level to only log failed calculations, in this case the trace level value should be set to "Errors".  With the value at All every calculation the server performs is then logged and looks like:
