Determine the number of weeks based on teh months/quarter selected *Date tabel has only Month data(

Hello,

I have a date table which only has Month level data ( year, quarter, Month). Based on the filter, need to calculate the number of weeks.

Single year will be chosen so, can start the week count from start of year. User can choose month from different quarters also. Or can choose a full quarter. If current month is also chosen, only completed week should be considered-Basically upto previous week.

Hi @suma2413 ,
Here is my test data and Steps you can try:

vheqmsft_0-1715939058360.png

Create measures:

startDateOfMonth = STARTOFMONTH('Table'[Year-Month])
endDateOfMonth = EOMONTH([startDateOfMonth],0)
Sum = 
IF(
    HASONEFILTER('Table'[Year-Month]),
    DATEDIFF([startDateOfMonth],[endDateOfMonth],WEEK),
    SUMX('Table',DATEDIFF([startDateOfMonth],[endDateOfMonth],WEEK))
)

Final output

Thsis helps, But still doesnt provide week count which are complete..Hence I introduced WeekNo and then wrote DAX to calculate only complete weeks.

I would suggest using a proper date table, this will make your life a whole lot easier. 

 

There are some great examples of extended date tables out there that can be created easily in Power Query. 

 

Here is a good article with some steps and a link to the code you can copy and paste.
