    Hi Anonymous,

     

    Please check the following steps as below.

     

    1. Create a calculated table and create two calcualted columns in it.

     

    dimtime = CALENDAR(MIN('sales'[date]),MAX('sales'[date]))

    weeknum = WEEKNUM('dimtime'[Date])
    year week = YEAR(dimtime[Date])*100+WEEKNUM(dimtime[Date])

    2. Create a new calculated table to get the result as we need.

     

    result = var yearweekt = YEAR(TODAY())*100+WEEKNUM(TODAY())
var yearweek12= YEAR(TODAY()+84)*100+WEEKNUM(TODAY()+84)
return
CALCULATETABLE(dimtime,yearweekt<=dimtime[year week] && dimtime[year week]<=yearweek12)

    For more details, please check the pbix as attached.

Hi Frank,

I have a calendar table made out of a minimum and maximum due date from sales table. This table contains date for 2 quarters at one time and keep updating regularly eg Q4-18 and Q1-19, Q1-19 and Q2-19, Every quarter the dates update. I need to make a week column in the Calendar table which gives me current week and 12 weeks as the output irresepective of the year. 
For example i want output  currently as Wk 46,47,48,49,50,51,52,53,01,02,03,04,05(I have dates from 1st oct-2018 to 31st march 2019 in calendar table).  Next week it should be changed to Wk 47till wk 06. 

Thanks

    Hi Frank,

    Thank you for the solution. I have one more thing, i am not able to put the weeks in order as 13 weeks , like 46,47,48,49,50,51,52,53,01,02,03,04,05. It is coming now as 01,02,03,04,05,46,47.....53. Is there any way possible that we can put them in order as i have shown above.

    Thanks
