minus from cumulative

[Anonymous]

Hello all,

I’ve been struggling all day on this and can’t find a solution.

I’m trying to work out how many workers my factory needs in the future.  I have a total each week that we need, [Weeks backlog efficiency Zoned] and a running total of the number of workers needed [Cumulative], but I want to minus off each value the number of workers we have [Past Staff] .  because we are behind I need to have a cumulative total and move what’s left to be made over into spare capacity next week ect hence the running total.

Cumulative =

CALCULATE([Weeks backlog efficiency Zoned],

   FILTER(ALL('Future Orders'[Yearweek Backlog 2-5]),VALUE('Future Orders'[Yearweek Backlog 2-5]) <= VALUE(MAX('Future Orders'[Yearweek Backlog 2-5]))))

When I minus off the number of workers [paststaff] it only takes it off the first week not every week so I end up with a growing number

I have made a cumulative Colum of the Work which needs doing:

Cummulative work =

(CALCULATE([Weeks backlog efficiency Zoned]    ,

    FILTER(ALL('Future Orders'[Yearweek Backlog 2-5]),VALUE('Future Orders'[Yearweek Backlog 2-5]) <= VALUE(MAX('Future Orders'[Yearweek Backlog 2-5])))))

and the difference between the Labour we have and the Labour we need:

+/- staff = [Weeks backlog efficiency Zoned]-SUM('D Labour (2)'[Past Staff])

this sits nicely in each “Yearweek Backlog 2-5”.  now all I need is a cumulative total of the +/-staff but it doesn’t work 😞

How are you minusing off past staff? Can you post that formula?

Sample data would help tremendously but I am guessing that it has something to do with your past staff only being in "scope" for that first set. Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

Hi thanks for the reply. I think your right about the scope, however even if I type in minus 7 it only takes it off the first week so I need to write something that repeats the process.  the past staff formula is below, it simply works out the full time days worked including overtime over the last 5 weeks.   Labour(2) is not linked to the date that the rest of the sheet uses. 

"PastStaff= (

IF('D Labour (2)'[Time period]="last5week",

IF('D Labour (2)'[Type of work] = "NoOfHeads",'D Labour (2)'[Value]*8,

IF('D Labour (2)'[Type of work]="Hrs Overtime",'D Labour (2)'[Value],0)

))/5)/37"
