Good morning everybody,
I hope you can help me solve the following problem:
the source table feeding my PBI report is extracted on Monday evenings from a system, and I have to calculate the new orders issued by the purchasing department in the last week. To do that, I thought of filtering the week number through the WEEKNUM function, but the WEEKNUM function starts counting from Mondays, so the instruction:
WEEKNUM(MAX([OrderDate]))
would only yield the orders issued on a single day, i.e. the Monday of the data extraction. Therefore, the agreed solution is to count the previous week orders too (8 days, but there comes the problem: how shoud I convince Dax 🙂 to pass two values to the WEEKNUM function, i.e. the last week plus the preious one ? I wrote the following filter:
WEEKNUM ( Orders[OrderDate] ) = OR ( WEEKNUM ( MAX ( Orders[OrderDate] ) ), WEEKNUM ( MAX ( Orders[OrderDate] ) )-1)
but obviously I get a message saying that Dax doesn’t support comparison between Integer values and True/False values.
What I want to obtain from my Count(OrderID), given that were 27 orders issued in week 49 and 31 orders in week 48, is 27+31 =58. Is it possible ?
I hope all the above sounds clear.

Solved! Go to Solution.
Have these new columns in Date Table, Week Rank is Important in Date/Week 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
These measures can help
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))
