Using task_status() function in a process model

davidh811 over 7 years ago

Hi,

I want to capture the status of a task and write it to a database. However, when I try to use task_status() as a paramenter, I get the following message in the server log:-

Expression evaluation error at function 'task_status': Error evaluating function 'task_status' : The function 'task_status' is unavailable.

I can use it quite happily in a report. Is this a known restriction?

Thanks,

David

I believe so have a look at forum.appian.com/.../Process_and_Report_Data.html it mentions The task metrics below are available for selection through the Expression Editor when defining a task report column of data.

Hi David,

I guess you will have to build a task report and then fetch the status of your task using a!queryProcessAnalytics() at runtime and write that in database thereafter.

@davidh Added to the above, task_status() is a metric of the task which will be available only under the context of the task and it couldn't be used as an Appian function.

Hi guys,

Thanks for your help - I have used a task report to get the task status.

It's now working perfectly!

Many thanks for your advice,

David
