aggr(sum(all <...> ...)) function over selections in QV v8.20
Hello,
I need some help with strange isue:
Task is to sum sales of a product over two out of three channels, when the product and only onechannel is selected. You can find an example attached, where "Product sales in channels AAA and BBB" is required field, when product and channel are selected (lets say x001 and AAA).
Strange thing is that this expression works on QV v9.0, but not QV v8.20 (whitch we still must use on server for a while). Is this QV bug or only lack of my experience?
