BEX Query - show previous period for calday

Hi SAP Experts

We would like to create from Inventorying Controlling infocube this in BEX query designer to use it in Analysis for MS Excel like this.

There is 0CALDAY in the row and two KFs in the column. In my oppinion offset is not possible to use because it needs variable.

                Quant from              Quant

                prev.day                Current day

01.01.2013      10 {from 31.12.2012}    150

02.01.2013      150{from 01.01.2013}    130

03.01.2013      130                     200
