Filter Data Based On Values Matching In Two Columns

Question

Is it possible to filter data based on values in two columns matching in Einstein Analytics? For example, I have one column named BO Qty and another named Supply Qty. If BO Qty is 1 and Supply Qty is 1 then I only want to show that row in my result.

If this is not possible I was thinking of another solution which would be to create a formula field that calculates one minus the other, and if the value = 0 then it is a match. I was trying to use this new formula column in the SAQL query but seem to also be running into some difficulty. Below is the query that I am trying to run.

q = load "FillRatio201902"; q = filter q by 'Allocated_Date' == "1/1/66"; q = filter q by 'BO_Qty' > 0; s = filter s by 'Formula1' == 0; result = group q by 'Allocated_Date'; result = foreach result generate q.'Allocated_Date' as 'Allocated_Date', count(q) as 'A', sum(q.'BO_Qty') as 'B', sum(q.'Supply_Qty') as 'C'; result = foreach result generate 'Allocated_Date', 'A', 'B', 'C', B - C as 'D'; result = order result by ('Allocated_Date' asc); result = limit result 2000;
