Is it possible to control the execution order of attribute calculations in RTC?

Robert Huet (23112884) | asked Jul 26 '16, 11:51 a.m.
I'm trying to capture the date that a work item was last moved to "Reopen" state as a calculated attribute.  Because the calculation script has no knowledge of previous state, I've seen recommended workarounds using a second calculated attribute to capture the previous state.  However, for this to work, the script for capturing the "LastReopenDate" has to run before the script that updates the "PreviousState".  Is there any way to control this order?  If not, is there still a way to make this approach work, or does this need to be done as a work item save follow-up action (using API extension)?

 Thanks Lily!  You are a huge help!  This was the information I was missing.

I don't know the official answer. But from my observation, the order of the calculated value provider scripts are triggered follows the alphabetical order of the attribute id.
