Calculated Column based on multiple filter criteria
Hello,
How to create a calculated column flagging whether or not a particular calendar Week is shared between two calendar months or not (end of month scenario), without considering Saturdays and Sundays.
I want to try with approach of distinct count of Month numbers for a Week - If it is 2, then YES, else NO.
Example:
Week 13 is shared between March and April discounting Sat and Sun, thus Yes is needed.
Week 17 is Not shared between April and May discounting Sat and Sun, thus No is needed.
Table Dim_Date
| Date | Week Number | Month Number | Weekday | Calculate_Week shared between months? |
| 04-Apr-21 | 13 | 4 | Sun | Yes |
| 03-Apr-21 | 13 | 4 | Sat | Yes |
| 02-Apr-21 | 13 | 4 | Fri | Yes |
| 01-Apr-21 | 13 | 4 | Thu | Yes |
| 31-Mar-21 | 13 | 3 | Wed | Yes |
| 30-Mar-21 | 13 | 3 | Tue | Yes |
| 29-Mar-21 | 13 | 3 | Mon | Yes |
| 02-May-21 | 17 | 5 | Sun | No |
| 01-May-21 | 17 | 5 | Sat | No |
| 30-Apr-21 | 17 | 4 | Fri | No |
| 29-Apr-21 | 17 | 4 | Thu | No |
| 28-Apr-21 | 17 | 4 | Wed | No |
| 27-Apr-21 | 17 | 4 | Tue | No |
| 26-Apr-21 | 17 | 4 | Mon | No |
I tried below code but it resulted into "No" for Week 13 above too. It does look fishy to me but unable to fix this. Any help would be great.
Calculate_Week shared between months? =
IF(
CALCULATE(
CALCULATE(DISTINCTCOUNT(Dim_Date[Month Number]),
ALLEXCEPT(Dim_Date,Dim_Date[Week Number])),
FILTER(Dim_Date,
OR( Dim_Date[Weekday] <> "Sun", Dim_Date[Weekday] <> "Sat"))
)
= 2, "Yes", "No"
)
Thanks

Hi Anonymous ,
Based on my test, if you use the following formula to modify your second method, the result is correct.
Column = VAR _week = [Week Number] RETURN IF ( CALCULATE ( CALCULATE ( DISTINCTCOUNT ( Dim_Date[Month Number] ), FILTER ( 'Dim_Date', 'Dim_Date'[Week Number] = _week ) ), FILTER ( Dim_Date, NOT ( Dim_Date[Weekday] IN { "Sun", "Sat" } ) ) ) = 2, "Yes", "No" )So I think it could be related to the context with ALLEXCEPT() —— The two groups of expression consider or ignore the filters made on related tables, respectively.As the official document said, ALLEXCEPT() removes all context filters in the table except filters that have been applied to the specified columns.

Thanks much for quick help. Really appreciate. It works exactly like required.
I used the FILTER syntax you provided and sourrounded it with ALLEXCEPT- this works
But ALLEXCEPT sourrounded by FILTER - this does not workWould be very helpful if you could explain a bit on this. Thanks in advance.
This works:Week shared between months = IF( CALCULATE( CALCULATE ( DISTINCTCOUNT(Dim_Date[Month Number]), FILTER(Dim_Date, NOT (Dim_Date[Weekday] IN {"Sun", "Sat"})) ), ALLEXCEPT(Dim_Date,Dim_Date[Week]) ) = 2, "Yes", "No" )This does NOT work. (Result of IF is 12 always)
IF( CALCULATE( CALCULATE ( DISTINCTCOUNT(Dim_Date[Month Number]), ALLEXCEPT(Dim_Date,Dim_Date[Week]) ), FILTER(Dim_Date, NOT (Dim_Date[Weekday] IN {"Sun", "Sat"})) ) = 2, "Yes", "No" )Thanks
