Querying task details... too quickly??

Thank you, all, for your input. I will give the timer node a try (I had been thinking along the lines of Sleep(5) but Appian doesn't run DOS Batch commands)

Yes, Your speculation seems appropriate! By the time Save Task Performance ran task completion was not marked complete in report, hence the issue.

This can be handled in 2 ways:

1. Adding a script task to query process report and an XOR node. Before the write records node system should check if data is available or not before Save Task Performance is executed. If its blank then process can retry the query.

2. If you are querying in the UIT then adding a timer between the User Input Task and Save Task Performance node.

Yes, this is a race condition where the data from the process execution engine is synced to the process analytics engines slightly after the next node was started. As far as I know, there is no transactional guarantee that exec and analytics are in sync.

After a user task completes, queryProcessAnalytics sometimes returns null data when queried immediately, but works fine when retried later.

The task wasn't found by the report since it wasn't marked complete yet and thus the expression that builds the record had no data to include"[/quote]

Yes, your speculation is correct - there's a timing gap between task completion and when the data becomes available in queryProcessAnalytics. Task completion and analytics data sync aren't instantaneous.

I would recommend, Add a 2 second timer node between the user task and the "Save Task Performance" node to allow time for data synchronization.

Process Analytics operates on a separate server that aggregates information.
