grouped percentage trending

[Rahul_SAS]

dear experts,

I am trying to create a dashboard having weekly trending of Sale percent Item Group wise and used the below mentioned dimensions:

Category:     Week

Measure:     Sale %

Group   :     Item Group

In result, it shows weekly share of Item group wise sale percent. Is there a way to have weekly total % as 100% not shared perecent total.

Regards

Rahul
