QlikView - How to

[#1]

Hello

I hope someone can help me with a query on QlikView.

We are using ServiceNow to log our tasks and incidents at work.

I am trying to create a dashboard showing when a call was responded and fixed and if it was within SLA.

From my attachment, the first screenshot, you ca see that an Incident has and Assignment group and Assigned to.

I have successfully created the logic to determine when the Incident metric has been allocated to the Incident Assignment group

Load *,
If([Incident Metric Definition])='Assignment Group' and [Incident Metric Definition] = 'Assigned to Duration' and [Incident Metric Value]=([Assignment group]),mi_start,null()) as Official_Start_Time
;

What I need help with is to determine the first time a member (Assigned to) of that Assignment group responded to that Incident.

On the second screenshot of the attachment you can see we have 2 [Incident Metric Value], Paul McGinnis and Andrew Boyd. Paul McGinnis and Andrew Boyd are both members (Assigned to) of the Assignment group OPS-Windows-Server. But Paul McGinnis responded to the call first at 2016-07-12 13:40:53, but as he is also a member of the Assignment group PS-TCS-Print my logic is not picking his start time up, but it is picking up 2016-07-14 12:51:02 for [Incident Metric Value] Andrew Boyd.  Please see my logic below.

Does anyone know of a way that I can use the above logic for the Official_Start_Time to also find the first (Assigned to) of the Assignment group OPS-Windows-Server.  To give me Paul McGinnis response time of 2016-07-12 13:40:53.

Any help would be appreciated.  I hope this makes sense to someone, I think I have waffled on a bit

Thank you

Stephen
