How do I count the number of days a project is in the same status?

[#1]

I collect the below data for multiple Clients, Project IDs, and Statuses. I want to be able to count the number of days that each project is in the same status. How do I do this with either a script or set analysis? The below data shows the statuses over time, but I only need to know how many days each project has been in the last status. In the below example calc I subtracted the dates 23-Apr-16 and 15-Apr-16 to get 18 days. I generated the below straight table using the Aggr function in the Expression.

Client	Project ID	Supplier	Status	Load Day	Last Status Days
Client A	12345	Supplier A	With Customer - Stakeholder	23-Apr-16	18
Client A	12345	Supplier A	With Customer - Stakeholder	22-Apr-16
Client A	12345	Supplier A	With Customer - Stakeholder	21-Apr-16
Client A	12345	Supplier A	With Customer - Stakeholder	20-Apr-16
Client A	12345	Supplier A	With Customer - Stakeholder	19-Apr-16
Client A	12345	Supplier A	With Customer - Stakeholder	18-Apr-16
Client A	12345	Supplier A	With Customer - Stakeholder	15-Apr-16
Client A	12345	Supplier A	With Customer - Legal	14-Apr-16
Client A	12345	Supplier A	With Customer - Legal	13-Apr-16
Client A	12345	Supplier A	With Customer - Legal	12-Apr-16
Client A	12345	Supplier A	With Customer - Legal	11-Apr-16
Client A	12345	Supplier A	With Customer - Legal	08-Apr-16
Client A	12345	Supplier A	With Customer - Legal	07-Apr-16
Client A	12345	Supplier A	With Customer - Legal	06-Apr-16
Client A	12345	Supplier A	With Customer - Legal	05-Apr-16
Client A	12345	Supplier A	With Customer - Legal	04-Apr-16
Client A	12345	Supplier A	With Customer - Legal	02-Apr-16

Hi Ed!

     Try having a straight table with dimensions:

Client, Project ID, Supplier, Status

And then have an expression like:

Max([Load Day]) - Min([Load Day])

Hope this helps!

I'm assuming a project can only have 1 status per day?

Unless your data volume is huge, you shouldn't have to take this logic to the script. What are the dimensions of the chart that you want to display this expression in? In the above example, you included Status and Date as dimensions, but I'm assuming that wouldn't be what you'd actually want? Assuming your only dimensions would be Client, Project ID, and Supplier, your expression would look this like:

max(aggr(

     if(Status=firstsortedvalue(total <[Project ID]> Status,-[Load Day]),

          [Load Day]

     )

     ,[Project ID],[Load Day]

))

-

min(aggr(

     if(Status=firstsortedvalue(total <[Project ID]> Status,-[Load Day]),

          [Load Day]

     )

     ,[Project ID],[Load Day]

))

+ 1

Edit: this is also assuming each project can only have one Supplier. If that's not the case, simply add Supplier to both your aggr() dimensions and your firstsortedvalue() subtotal.
