Use count with look up and an if argument

[theblueslover]

Hi All,

I have two tables which are related by CurveId. I want to calculate how many of the rows whose Score in Table 1 fall in between "From and To" in Table 2 and put the total count against each row under the TotalCount column.

As in the example below, there are 2 rows in Table 1 whose scores fall in between 4% and 10% in CurveId 1 in Table 2, and there are 3 rows in Table 1 whose scores fall in between 10% and 20% in CurveId 1 Table 2.

Table 1
TransactionId	CurveId	Score	TotalCount
1000	1	2.00%	1
1000	1	7.00%	2
1000	1	8.00%	2
1000	1	15.00%	3
1000	1	16.00%	3
1000	1	20.00%	3

Table 2
CurveId	From	To
1	0%	4%
1	4%	10%
1	10%	20%
2	0%	8%
2	8%	15%
2	15%	20%
2	20%	25%

I have tried the expression below but it just returns 1 against each row.

CALCULATE(
                    COUNT(Table1[TransactionId]),
                    FILTER(Table2, Table1[Score]>=Table2[From]&&Table1[Score]<=Table2[To])
)

Any help will be greatly appreciated.
Thank you.

Hi Stephen,

Thank you so much for your reply. what I would like to achieve is to add this as a column in Table 1 where we can see the transactions. So following from the same example, TotalCount column is a calculated column and we can see the total number against each line item.

Table 1
TransactionId	CurveId	Score	TotalCount
1000	1	2.00%	1
1000	1	7.00%	2
1000	1	8.00%	2
1000	1	15.00%	3
1000	1	16.00%	3
1000	1	20.00%	3

Kind regards,

Hi @theblueslover ,

You could try this measure.

Count =
CALCULATE (
    COUNT ( 'Table'[CurveId] ),
    FILTER (
        'Table',
        [Score] <= MAX ( 'Table (2)'[To] )
            && [Score] > MAX ( 'Table (2)'[From] )
            && [CurveId] = MAX ( 'Table (2)'[CurveId] )
    )
)

You can check more details from here.
