Hi,

 

Try this

 

=[Sales]-CALCULATE([Sales],FILTER(Calendar,MAX(Calendar[Table])-7)

 

I have assumed that the dates in your visual have been dragged from the Calendar Table.  There should be a relatiosnhip between the Date column of your source data table and the date column of your Calendar table.

 

Hope this helps.

The date is a column from database

Hi @ApurvaKhatri

 

The trick is get an index calculated column to sort Weeks. (You can use power query)

 

This is the result

And the measures in my case are...

 

Total Sales = SUM(Sales[Sales]) 
Total Sales PW = 
var thisweek = FIRSTNONBLANK(Sales[Index];1)
var prevweek = LOOKUPVALUE(Sales[Index];Sales[Index];thisweek-1)
return
CALCULATE([Total Sales];ALL(Sales[Date]);Sales[Index] = prevweek) 
Variance = [Total Sales] - [Total Sales PW] 

I hope this helps

Hi @BILASolution and @Ashish_Mathur

 

I cannot share the exact data.

But I would give you an idea hat I am trying to acheive

 

Table : Sample

Columns : PrincipalBalance (It is amount 1000, 24000, 32448, 767778) , Date (It contains everyday dates), Number(it has values negative, positive i.e 0.76, 0.4,-8.6, 75.0, 23, 5.4, 4.3 .... ), ID

 

I have created calculated column :

Day Of week = FORMAT ( Sample[Date], "dddd" ) - To extract the week day names from Date column

Date Select = if(Sample[Date] = "Wednesday",Sample[Date],Blank())  - I need the sum(PrincipalBalance) every wednesday for entire week starting Thursday to Wednesday. i.e 10/25/2017 - Wednesday sum(balance) from 10/19/2017 - 10/25/2017.

 

I have created measures:

 

Current = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number]< 1))

1-2 Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] < 3))

3-4 Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] < 5))

5+ Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] >= 5))

Sum = Current + 1-2 Weeks + 3-4 Weeks +( 5+ Weeks)

 

Data Display

 

Matrix

Rows: Date Select

Column: Months(Date)

Values: Sum

Now I need the difference between 25th Oct and 18th Oct, 18th Oct and 11th Oct and so on...

 

 

Number        Balance       Date

0.00              1000            10/24/2017
0.00               2000            10/16/2017
1.00     7000                      10/10/2017
0.00      1000                      10/27/2017
0.00       2000                      10/17/2017
1.10        5000                      10/24/2017
-6.57        3500                        10/10/2017
17.61        2500                         10/2/2017

 

I need to acheive this. 

Please Help.

 

Thanks alot for your time

Hi @ApurvaKhatri,

 

No one here is intested in your actual data.  Dummy your dataset and then share the result of that dummy dataset.  The dataset that you paste here should be such that can be easily copied into an Excel file.

Hi,

 

What is the use of the Number column?  I thought you just want to add the Balance column on every Wednesday and then take the differrence over the previous week.  Please show the actual result you are expecting based on the data that you pasted above.

Hello @BILASolution

 

In my case, Total Salea is a measure.

 

Will this solution still work?

 

Thanks,

Apurva Khatri

Hi @ApurvaKhatri

 

Sure, In fact [Total Sales] is a measure in my case.

Thanks for the solution. But in my case, sales is a measure so its not working
