How to compare the same ratio in different periods

Hi,

I would like to know whether it is possible to compare the same ratio but in different periods.

For example, I have the 0INV_QTY and I would like that in case I select 0FISCPER with this range, for example, [001.2015:002.2015], I had the same 0INV_QTY ratio showing the 0FISCPER [001.2014:001:2015].

Is it possible to achieve this from the Query Designer? or.... perhaps from BW?

Thanks a lot in advance.

Regards.
