Set Analysis

[#1]

Hi,

I am trying to write a set analysis expression like below:

=Sum({<FIS_CAL_WEEK_ID ={">=Max(FIS_CAL_WEEK_ID)-12 <=Max(FIS_CAL_WEEK_ID))"}>} TOTAL_QTY)

The objective sum of Total Quantity where it will start from Maximum week number and will show only 13 weeks in the chart.

Thanks
