SUMX: Count unique records in a table (ignoring blanks blank rows)

[circledchicken]

Hi PowerPivot experts,

I am beginning to learn how to use PowerPivot and this question is based on the last 'Useful' example in this post:
SUMX() – The 5-point palm, exploding fxn technique « PowerPivotPro

I have a table named Table1 that looks like this:

	A	B
1	Product	Store
2	Apples	1
3	Oranges
4	Pears	1
5	Apples	1
6
7		2
8	Apples	1

<tbody>
</tbody>

Excel 2010

I have two measures defined as follows:

• Count of Stores:
  =DISTINCTCOUNT(Table1[Store])
• UniqueCombinations:
  =SUMX(DISTINCT(Table1[Product]), [Count of Stores])

In my PivotTable, the only element is the 'UniqueCombinations' measure in the Values section. Currently the value of the measure is 5 corresponding to these rows:

	A	B
1	Product	Store
2	Apples	1
3	Oranges
4	Pears	1
6
7		2

<tbody>
</tbody>

My question is, how do I adjust the measures to exclude any rows where all the corresponding columns are blank? I would like my UniqueCombinations measure to return 4 in this case (excluding row 6).

I know I could create a calculated column for example and then count non-blanks on that (using something like =COUNTAX( DISTINCT( Table1[CalcColumn] ), Table1[CalcColumn] ). However I would like to learn how to do this using purely measures if possible.

Many thanks for your time.
