Aggregating over data sets

[Dayna]

Hello,

I'm very new to PowerBI (come from a QlikView background) and attempting to calculate the 'absence' of data. We have a set of records for someones timesheet, and I want to work out the amount of 'day job' for that person, for that day. Day job is calculated by the sum of time for that person, for that day, and subtracted from 7.5. 

My data set looks like this:

Date	Person	Type	Hours
10/07/2018	Joe Bloggs	Support	4
10/07/2018	Joe Bloggs	Project	2
11/07/2018	Joe Bloggs	Support	4
11/07/2018	Joe Bloggs	Project	2
11/07/2018	Bob Smith	Support	2
11/07/2018	Joe Bloggs	Project	2
10/07/2018	Bob Smith	Support	1
10/07/2018	Joe Bloggs	Project	5

So for example, on 10/07/2018, Joe Bloggs did 4 hours support, 2 hours project, therefore 7.5 - 6 = 1.5 hour day job. 

I have no idea where to start with PowerBI with this, and would really appreciate some assistance!

Many thanks in advance,

Kind Regards,

Dayna

Just create a measure along the lines of:

Measure = 7.5 - SUM('Table'[Hours])

Then just put that into a table visualization along with the other columns that you want to summarize by.

That was easy! Thanks for the help!
