I got one question regarding PrdocutDimension in ProductScope Campaign Criterion.
Basically, both a shooping campaign and a display campaign with GMC feed can have product scopes. but they use different ProductDimensions: for example, shopping campaign use
ProductType dimention while display campaign with a GMC feed uses
ProductTypeFull dimention. I found
ProductType and
ProductTypeFull is quite different:
1. in a shopping campaign, it can have at most 5 levels of
ProductType dimension (there are hierarchy here and they will be treated as product_type_L1 to product_type_L5 when calling adwords API to fetch them). see below

2. in a display campaign with a GMC feed, it can have at most 7
ProductTypeFull dimension (please see below) and there are no hierarchy here (all of these 7 are treated as ProductTypeFull when calling adwords api to fetch them). what's the relation for these ProductTypeFull dimensions? in which scenario we should use multiple ProductTypeFull here? the doc is unclear.

Thanks in advance.
Thanks,
Jianbo
