buy 2 from x category +1from y category get overal automatic 5% discount

hi i'm trying to setup a 5% automatic discount if a customer buys 2 items in a category + 1 item in a different category. how can i manage to do this?
thank you in advance

Hello,

You would need to use a parent coupon. Here is how:

Coupon A:
Function Type > coupon
Value > 5%
Minimum Product Quantity > 2 specific
Asset > select category x

Coupon B:
Function Type > coupon
Value > 5%
Asset > select category y

Coupon C:
Function Type > parent coupon
Process Type > Only if All apply
Asset > add coupon A and B

Then add Coupon C to the automatic coupon list
