Hi All,
I have removed Timestamp (Date) columns and using DateKeys in Fact Tables . I need to update few measures from Date to DateKey. I have below measure (MOM) but facing issue while using DateKey. Is there any workaround (( I need to convert yyyyMMdd to Date while adding to DateAdd Function)
[Total Sales] = CAlCULATE(SUM('FactSales'[Sales]))
MOM Sales : (CALCULATE([Total Sales],ALL('Is Latest'),TREATAS(VALUES('Is Latest'[FactSalesLatestDateKey]),'Date'[DateKey]))/(CALCULATE([Total Sales],ALL('Is Latest'),DATEADD(TREATAS(VALUES('Is Latest'[FactSalesLatestDateKey]),'Date'[DateKey]),-1,MONTH))))-1
Note: We keep 2 months daily data and remaining months as monhtly data ( aggregate daily data to single day( last day of month)) in FactSales
FactSales:
DateKey | Product | Sales |
20220101 | A | 100 |
20220102 | B | 200 |
… | ||
20220201 | A | 300 |
20220202 | B | 400 |
Date: Marked as Date Table ( Date Column as UniqueIdentifier)
DateKey | Date |
20220101 | 1/1/2022 |
20220102 | 1/2/2022 |
….. | |
20220201 | 2/1/2022 |
20220202 | 2/2/2022 |
Is Latest: this Table tracks Latest datekey in fact tables
Is Latest |
FactSalesLatestDateKey |
20220202 |
Relationships:
FactSales * (DateKey) --> 1 Date (DateKey)
FactSales * (DateKey) --> IsLatest(FactSalesLatestDateKey)
Thanks,
Abhiram
@abhiram342 , Date table has column that is date, which you have used to mark it as date table use that
Assuming date is joined with date table
Last Month = CALCULATE(SUM('FactSales'[Sales]), dateadd('DAte'[Date],-1, Month )
We should use date from date table.

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
