Cumulative Sum on script

[Anonymous]

Hello,

i would like to do a cumulative sum of the last 12 months on the script.

the dimensions i have are date, family and product.

so for example for 201702 it should do the sum of sales of the same family and product from 201603 to 201702.

¿how could it be done?

thank you
