Hi,
I have a matrix that I am tracking instances of purchases and deductions by suppliers by period.
What I need to do is to identify an variances by period & by supplier.
E.g. Each Period needs to show by supplier a 0 (Nil), -1, +1 (or some other variable) to identify if the count of purchases match the count of deductions in the file, and ignore any 0 (nil) values.
A sample of what I am looking to get at is below along with a simplified sample database.
(Note, I don't need the Grand Total)
I am new with DAX, and it seems I have hit my mental block with this one 🙄.
