Update of measures Excel Power Pivot

[Sandrinetayli]

Hi, 

I created a database with lots of data but to be able to send it to each team members (I did not want them to have access to others’ data), I had to split the master workbook by name of the team members. However, here is my problem: 

On my Master I have two columns; 

one is called time period: 

A2210 (A for actual) 

A2110 (A21 for Last Year)

B2210 

A2209 (B for Budget)

A2109

B2209

the other is called Amount 

100

93

80

120

110

90

(this is an example) 

now, I created two formulas for my Query (I’m very beginner so please don’t judge me :face_with_tears_of_joy:). Expense ES is my table with the costs and, Time Period is my table with the time period (I separated both of them in the formula because I am using a slicer and I needed to create relationships) 

Var (-) = Calculate(sum(Expenses ES), time period=A2210) - Calculate (sum(Expense ES), time period = B2210) 

Var % = Calculate(sum(Expenses ES), time period=A2210) / Calculate (sum(Expense ES), time period = B2210) -1 

here comes the issue: this formula is very static which means that I would have to update by hand each month for ex: now in November I will have to update for 25 workbooks A2211 and B2211. 

do you have any idea on how to avoid this, I can’t change the date format (A22 etc… because it comes from a different software… 

hope you will be able to help… thank you

What you need (I think, although it's a bit difficult to picture exactly what you have here without a sample of the actual)... what you need, I think, is to make use of the INDIRECT function, so that you can change a single cell, off to the side, to contain the month. (10 for October, 11 for November, etc). And then INDIRECT uses that to construct the full formulas in each case.

Here's a useful reference for understanding how INDIRECT can be used.

Hi Mathetes,

My table would be as follow. As you can see I have different time period in the same column, different amount depending on the account and account name. That’s why I find it very hard to find a code that would not require to update each month the formulas.
As stated earlier, now I have to use this formula all the time for variance:
Calculate(sum(Expenses[amount], time period =“A2201”) - calculate(sum(Expenses[amount], time period =“B2201”)

And for the % I had to create two different formula which also complicate my formulas
On that divides Actual and Budget and the other one that gives the variation:

Div = Calculate(sum(Expenses[amount], time period =“A2201”)/calculate(sum(Expenses[amount], time period =“B2201”)
And, on another formula
[Div] - 1


TIME PERIÓD AMOUNT ACCOUNT ACCOUNT NAME
A2101 100 PAYROLL WAGES
B2101 250 PAYROLL WAGES
A2201 200 PAYROLL WAGES
B2203 100 RENT MADRID
A2203 430 RENT MADRID
A2103 608 RENT MADRID
A2101 80 PAYROLL PART TIME
B2101 70 PAYROLL PART TIME
A2201 45 PAYROLL PART TIME
B2203 80 RENT BCN
A2203 90 RENT BCN
A2103 56 RENT BCN

Thank you in advance

For the current date you may use in parameter

"A" & FORMAT(TODAY(), "yymm")

Or load into the model table "par" with the column "Month" and only one value which is text like "2211". When

"A" & VALUES(par[Month])

Something like

= VAR periodA = "A" & VALUES( par[Month] )
  VAR periodB = "B" & VALUES( par[Month] )
  VAR sumA = CALCULATE( SUM(Expenses[amount], time period =periodA)
  VAR sumB = CALCULATE( SUM(Expenses[amount], time period =periodB)
RETURN
 DIVIDE( sumA, sumB, 0 )
