"QP: Pricing Party Hierarchy Type" and "OZF : Relationship Type for Buying Group"

when you use in a same time QP and OZF module, you manage 2 relationship

• "QP: Pricing Party Hierarchy Type" and
• "OZF : Relationship Type for Buying Group"

In OZF you can manage a qualifier (market eligibility) with a "party id" but you are unable to manage the "apply to hierarchy"  checkbox  (this check box is present in QP screeen).

In OZF, the buying group in mainly use to manage indirect customers.

I forecast a test, but in several weeks and I have 3 questions (i hope you have some answers) :

-> in OZF, how can i setup the "apply to hierarchy" checkbox

-> in QP & OZF, can i use 2 hierarchies (from QP & OZF profiles options)
