AGGR with additional dimension

[saggroad]

Hi

In the below aggregation which works well  I also want to add only 'NEW' products (TYPE = "NEW').

Could someone tell me how would I include also TYPE = 'NEW' in the below aggregation so that it only sums up 'NEW'

=-

sum(aggr(distinct only(INFPERIOD)='$(vInforceMonth0)',Value))

Thank you!
