SUMPRODUCT Power Query to filter blanks

[bilogin]

Afternoon,

So I've added a pivot table as a data source which looks like this:

Concat	1801	1802	1803	1804	1805	1806	BLANKS
fn123410022		12		36	87	7	FALSE
fn1324510022							TRUE
fe1352168751	1		6		8	4	FALSE

Concat = Product Code

1801, 1802 etc = Months of the year

In Excel, I would paste the pivot into a new tab and add the BLANKS column to see whether the product had been sold. The formula is: 

=SUMPRODUCT(--(B836:AF836<>0))=0

Is there an alternative I can use?

Secondary question: I'm using a pivot table as source data which would be updated one a month to include new sales data. If I create a Custom Column like the one above, would PBI know to insert a column for the new month or would it override the Custom Column?

@bilogin , it should unpivoted

Also, share the expected output. Not clear with excel formula

@amitchandak the expected output for the SUMPRODUCT formula is as in the table - if the rows are blank or less than 0 (ie no sales have taken place), the formula will return TRUE. If the value is >0, the cell will return FALSE.

Pivoting the data didn't work, I tried Sales to Period even though both are numbers, I got the following error:

Expression.Error: We cannot convert the value null to type Text.
Details:
Value=
Type=[Type]

Thanks for your help.
