## Calculate Purchase frequency

Hi everyone, I cannot understand why the total does not SUM correctly.
In the following table I am making measurements of:
Id_Name = Distinctcount (Table1 [Id_Name]) ... OK
Sales Check = Distinctcount (Table1 [Id_SalesCheck]) ... OK
here I can not show what is seen in the table.
2 or more Purchas = If (Sales Check > 1, Distinctcount (Table1 [Id_Name]), BLANK())
I tried SUMX but the result was an out-of-itself number.
SUMX (Table1, Distinctcount (Table1 [Id_Name]))

I try to do my best but I'm really frustrated, I need help

This next table make in Excel and Show how I want to see, really I want to correctly sum total.

Try measure as below:

``Measure = SUMX(VALUES('Table1'[Id_Name]),'Table1'[2 or more Purchas])``

## Re: Calculate Purchase frequency

Try something like this:

``````Measure 2 =
COUNTX(
FILTER('Table',
'Table'[Sales Check] > 1
),
'Table'[Sales Check]
)``````

The issue is your measure works fine and it is doing what you asked. Remember measures are recalculated for every place they are used.  The total lines do not have a different formula that just sums what is above it. It recalculates the measure based on the filter context of where it is, which is the total line with no filters for the ID. So, in your total, the measure is recalculating and doing this:

1. Is sales check > 1? Well, what is sales check on the total line? It is DistinctCount(table) - on the total line, that is the entire table. So the distinct count is 158. So yes, 158 > 1, so the result is True.
2. Therefore return DistinctCount(table) which is 158, and that is what you see.

## Re: Calculate Purchase frequency

Basically, there's a filter context on each row of your table, e.g. ID_Name = 1 is the filter context on your first row. But the issue is with the Total as there's no such filter on that.

Here you can try use HASONEVALUE to check if Id_name has single value. If it's return false, it means you are on "Total" row, which means there's no Id_name filter on that and it returns all values.

I might suggest you take a look below, which might help.

@GKs , Try like

``countx(filter(summarize(Table1,Table1[id],"_1",[Sales Check]),[_1]>1),[id])``
