This week date measure

[Anonymous]

Hi ,

can we create a measure to return all the dates that belongs to this week ? and last year same week ? 

this week dates =

var todaydate = TODAY()

var startdate= CALCULATE(SUM(DimTimeCalendar[WeekPeriodStarting]),DimTimeCalendar[Date_Key]=todaydate)

var enddate= CALCULATE(SUM(DimTimeCalendar[WeekPeriodEnding]),DimTimeCalendar[Date_Key]=todaydate)

RETURN

DATESBETWEEN ( Dimtimecalendar[date_key], StartDate, EndDate )

Like this i am using right now and storing it in a calculated table . Is this the right way ? or we can use a better way to do this .

let me tell you my original problem .. so i need in a tabular format this week sales and last week sales . in a same table 

kind of like this .. lw means last week . and i am giving the dax also 

GP$$ = SUM(FactSales[GpFexchangeRate])

GP Lw =

CALCULATE(

FactSales[GP$$],all(FactSales),

FactSales[Sale Date]=SELECTEDVALUE(FactSales[Sale Date])-7)

GP this week =

var datetoday=TODAY()

var thisweek=calculate(max(DimTimeCalendar[Fiscalweeknumber]),filter(all(DimTimeCalendar),DimTimeCalendar[Date_Key]=datetoday))

var thisyear=calculate(MAX(DimTimeCalendar[FiscalYear]),filter(all(DimTimeCalendar),DimTimeCalendar[Date_Key]=datetoday))

return

CALCULATE(

sum( FactSales[GpFexchangeRate]),

DimTimeCalendar[Fiscalweeknumber]=thisweek,DimTimeCalendar[Year]=thisyear

)

Is this the right way ? i am new to power bi . please help me to find a better solution

Hi @Anonymous ,

I think you want the matrix to show the values for this week and the previous week.

Here's my solution.

1.Create a calendar table.

Calendar = CALENDAR(MIN('Table'[Date]),MAX('Table'[Date]))

2.Create a measure, put it into visual level filters and set show items when the value is 1.

Measure = var _thisweek=WEEKNUM(TODAY(),2)
var _week=WEEKNUM(MAX('Calendar'[Date]),2)
return IF(_thisweek=_week||_thisweek-1=_week,1)

As shown above, the view shows the data for this week and the previous week.

Hi Stephen, i am trying to create a filter that once i click on it it will show me "This Week" and "This Month."

This example got me pretty close but wondering if you could me.

Thank you,

Pablo

Hi @PabloGiraldo 
Could you please clarify what these periods of time mean?
Does "today" refer to the day the user looks at the report?
Does the current week start on "today" and last -7 days?
Does the current month start on "today" and last -30 days?

[PabloGiraldo]

"Today" referes to the day the user looks at report.

Current week will be Monday through Friday. So taking this week as an example, current week will be May 15th through May 19th.

Current Month will be May 1st through May 31st.

Thank you!

It is difficult to produce a slicer you are interested in because the periods are included in each other.
There is the option of a generic slicer
The relative date.
My recommendation is to simply use it:

@Anonymous . Last year same weekday or same week

measure

week Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,DAY))

OR new columns in date table 

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

measures
This Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))

or

Last year Week= CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -53)))

Last year same week  = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Year]=max('Date'[Year])-1 && 'Date'[Week] = Max('Date'[Week])))
