Monthly budget divided by monthly working days

[Anonymous]

I have a date table where one column is all dates, another column is titled "working days" which has a 1 on business days and a 0 on weekends and holidays.

I have a budget table that has 12 rows.  One column is titled date which has rows like this 1/1/2106, 2/1/2016, 3/1/2016.....  Another column is titled "Budgeted Margin $", which has a total monthly budget number.  I want to build a chart like attached.  the red line represents the daily goal to hit the monthly budget and the black line represents the MTD actual.

My issue is the red line.  I believe I need to add a column to my date table with something like this  "Daily MTD Budget = sum(budget[Budgeted margin $])/sum(date[working days])............  and the column would of course divide the monthly budget number by the amount of working days in that month and do a running MTD budget number for each working day.

I hope this makes since.

According to your description, you have monthly budget target, now you want to create MTD daily target. Right?

In this scenario, I suggest you add a month column in both tables. Then build relationship on month column (Many to one). 

In date table, add a calculated column for Current Month Target.

Current Month Target = IF('Table'[WorkingDay]=1,RELATED(Table1[MonthlyBudget]),0)

Then add a calculated column for Daily Target.

Daily Target = 'Table'[Current Month Target]/CALCULATE(SUM('Table'[WorkingDay]),ALLEXCEPT('Table','Table'[Month]))

Now you can create a measure to calculate MTD.

MTD target = TOTALMTD(SUM('Table'[Daily Target]),'Table'[Date])

The result looks like below:

Thank you for your help on this.  This is what I have so far.  I'm on the step of adding a calculated column to my DateDimension table.......

Current Month Target = IF('Table'[WorkingDay]=1,RELATED(Table1[MonthlyBudget]),0)

.........but after  ,RELATED(..............it's not allowing me to enter the 'Budget' table.

Does anyone want to take a swing at this? I can also setup a table in our database differently to help get me to my end result of tracking daily budgets.

His formula needs to include the two tables' relationship columns, I had same type of issue with working with two tables and their columns in a formula.  

Mtg Column =

VAR Mtg = CALCULATE(VALUES('STEP Projects'[PM/AppTransitionMtg]), TOPN(1,FILTER('STEP Projects','STEP Projects'[Id]='STEP Resource Planning'[Project Online NameId])))

RETURN

IF(ISBLANK(Mtg),BLANK(),[Start])
