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