11 Week Look Ahead Dynamic Calculation

Hello!

 

I am stuck and I am really hoping that someone can help me write the DAX for the column to get the right results. Or advise on how to do this. I have a Scheduled Start Date column for when work orders are supposed to begin. For my dashboard/visuals I need to look ahead 11 weeks from Monday of each week and I only want the DAX to return the dates in week 11. I also need it to be dynamic so as the weeks progress it keeps looking ahead at week 11. 

 

As a side note, I was successful in writing DAX for a Week Start Date and a Week End Date column to group them. Now I am stuck. 


Thank you in advance for you help and advice on how to solve this!!

Hi, @emae613 

 

You can create this summary table, or use it as a table filter in other measures.

Like this:

Two columns first:

weekday = WEEKDAY([Date],2)
weeknum = WEEKNUM([Date],1)
Table1 = 
VAR a =
    MAXX ( FILTER ( ALL ( 'Table' ), [Date] = TODAY () ), [weeknum] )
RETURN
    SUMMARIZE (
        FILTER (
            ALL ( 'Table' ),
            [weeknum]
                = MAXX ( FILTER ( ALL ( 'Table' ), [weeknum] = a + 11 ), [weeknum] )
        ),
        [Date],
        [weekday],
        [weeknum]
    )

Hello@emae613 

 

Because I don't know what your requirements are used for, so I just created a table.

You need to create table by new table button.

Can you share your formula and error screenshots in the report? If you can describe in detail how your needs are presented in the report visual, I can help you more specifically.

Hi,

Try creating this kind of measure:

11weeks = var _sdate =CALCULATE(MIN('Calendar'[Date]),ALL('Calendar'[Date]),
WEEKDAY('Calendar'[Date],2)=1,
WEEKNUM(TODAY())=WEEKNUM('Calendar'[Date]),
'Calendar'[Date]>TODAY()-7)

var _edate = _sdate + 7*11
var cdate = MAX('Calendar'[Date])
return
IF(cdate>=_sdate&& cdate<=_edate,1,0)
 
Then place it here:

Thank you! I was able to create the table. Thank you so much and I apologize for my delayed response to this. So would I just use the scheduled start in the newly created table to filter by the t-week? Also, for some reason I'm not able to copy and paste anything into these text boxes. It gives me an error everytime. 

@emae613 

 

You can have a try. I'm not sure which way you created the table in the end, please explain the problem in detail.

Thank you! Ok I am very green in Power BI and completely self taught. What is a summary table? I was able to successfully create the first 2 columns as you listed above the Weekday and Weeknum columns. I went to add a new table and when I got to this portion: ( 'Table' ), [Date]

it gave me an error. I was trying to load my Scheduled Start Date table in that spot but it gave me a syntax error. It is loading 'Scheduled Start Date'.Date so I am thinking I am doing something wrong but it is making me select .Date. Hopefully that makes sense. 

@emae613  Any updates?

@emae613 ,

 

Week =
var _max1 =  today()  // or use maxx(allselected('Date'), 'Date'[Date]) //
var _stweek = _max1 +-1*WEEKDAY(_max1,2)+1 //add plus 7 for next week start date
var _edweek= _max1+ 7-1*WEEKDAY(_max1,2) +(7*11)
return
calculate(sum(Table[Value]), filter(date, Date[Date] >=_stweek && Date[Date] <=_edweek))
// or use all date
//calculate(sum(Table[Value]), filter(all(date), Date[Date] >=_stweek && Date[Date] <=_edweek))

 

You might have use independent table in case you select a date
