SLA - Based on varying priority, add time to a date excluding non working hours

[Legacy 320862]

Hi

If a job is logged at 13/03/2015 16:00:00 (a Friday), and is priority 1, then the job must be completed within 24 working hours.
If a job is logged at 13/03/2015 16:00:00 (a Friday), and is priority 2, then the job must be completed within 48 working hours.
(there are 5 priority levels)

I currently have the 'deadline' cell populated with this formula to work out, based on priority, how much time to add on to create the deadline, however, how would I exclude non working hours? :

=IF($D11=1, $C11+$K$8, IF($D11=2, C11+$K$7, IF($D11=3, C11+$K$6, IF($D11=4, C11+$K$5, IF($D11=5, C11+$K$4, " ")))))

D11 is the priority of the task (1,2,3,4 or 5)
K8 - K4 are the different times allowed to complete the task.
C11 is the time the job is logged.

I can send a spread sheet if this helps to explain?

Thank you so much for your help!
Jen

What are the values in K4-K8

 

[Legacy 320862]

K8 is 08:00:00 (8 working hours, 24 actual hours)
K7 is 16:00:00 (16 working hours, 48 actual hours)
K6 is 24:00:00 (24 working hours, 72 actual hours)
K5 is 32:00:00 (32 working hours, 96 actual hours)
K4 is 32:00:00 (32 working hours, 96 actual hours)

These are the times allowed based on the priority of the task. Priority 1 (K8) must be completed within 8 working hours. (apologies, my original message said 24 working hours by mistake, this should have been just 24 hours, which is 8 working hours)

I hope this helps to explain.
Thank you

Try this, J4-K8 is a small table with Priority No. & Times

=WORKDAY(C11,VLOOKUP(D11,$J$4:$K$8,2)/24)

Thanks for your help, unfortunately I am getting #N/A with this formula. I there a way I could send you my spread sheet?

I think the problem is that K4-K8 are in this format - "01/01/1900 00:00:00" - custom [h]:mm:ss and I don't know how to get this to display 8,16 hours etc. I can only get it to show 24, 48 etc hours.

You can upload the file to Dropbox, then post the link here.

Thank you so much, you will see it's slightly different to as described, I was trying to simplify the question when explaining in the first instance. I hope this makes sense.

Try this
=IF($D11=1,WORKDAY( $C11,$K$8), IF($D11=2, WORKDAY(C11,$K$7), IF($D11=3, WORKDAY(C11,$K$6), IF($D11=4, WORKDAY(C11,$K$5), IF($D11=5, WORKDAY(C11,$K$4), " ")))))

Brilliant, I think we're very nearly there. I've put that formula into G11, but the display is showing 16/03/2015 00:00 instead of 16/03/2015 10:20, do you know how I would get the times to display correctly please?

I can't thank you enough for your help on this, you are a genius! thanks

This one is better, picks up the time aswell

=WORKDAY(C11,INDEX($K$4:$K$8,MATCH(D11,$B$4:$B$8,0)))+MOD(C11,1)

You will need to change the Rating to JUST
