Sales comparision of today and last year today on Vertical table

Hi everybody,

I have such scenario that client wants to see sales values of two columns. Left shows sales of current date and the right will show the last year today .

How can I construct variables here lets say the last day today as dimension and body part related sales of last year today.

The display would be like

Brand 01.08.2013 01.08.2012

Regards.

Eddy.
