Dear all,
I'm using the following expression, but I aim to know how it works. Let me add more detail: in my intention,
I would sum all the purchase values till August (MY_MONTH) or other selected month
aggr(sum({<PURCH_MONTH={"<= $(=only(MY_MONTH))"}>} PURCHASE_VALUE),MY_YEAR, MY_SUPPLIER)
It seems correct, because I get the required values.
Now, I need to calculate another value but for PURCH_MONTH < MY_MONTH.
I was convinced that I could do it changing the condition <PURCH_MONTH= {" < $(=only(MY_MONTH))......
but it doesn't work.
Does anyone know what I'm doing wrong ?
Thanks in advance
stefan
