Helper ICalculate with TOPN
I have a table like this
TableA
| Promotion | Commission | Sale date | Sale ID | Product ID |
| PromoA | 10 | 21 Dec 2021 | 123 | 1 |
| PromoA | 10 | 29 Dec2021 | 124 | 1 |
| PromoA | 8 | 5 Jan 2022 | 125 | 2 |
| PromoB | 15 | 16Nov 2021 | 122 | 2 |
Table B
| Product ID | Product Description |
| 1 | TV |
| 2 | Camera |
I need to calculate total commission by Promo for first 10 sales where product category is TV and sale date is between 1 Sept 2021 to 31 Dec 2021 and where Commission is not zero.
I wrote the measure as
_Regina , Try like
Measure =
Var _1 =
CALCULATE (
SUM ( [Commissions] ),
DATESBETWEEN (
[Sale date],
DATE ( 2021, 09, 01 ),
DATE ( 2021, 12, 31 )
),filter(TableA ,related(TableB[Product Description])="TV" && TableA[Commissions]<>0))
return
Calculate( _1, TOPN(
10,
allselected(TableA[Sale ID]), _1
DESC
), Values(TableA[Sale ID]) )not clear on need to switch
