iprocurement smart form restriction to a Responsibility

Hello

I have a smart form in i procurement. I can assign to an organization(OU) but not a responsibility.

Can any one advise on if we can restrict to a resp.?

We are on 12.2.3. I created a local content zone and restrict that content zone CZ1 to an Organization.(eg: OU1)

Then I assigned a store ST1 to this content zone. The smart form SF1 is assigned to this store ST1.

The smart form SF1 belongs to more than 1 organization,(OU1, OU2, OU 3 etc.,)

Say we have Resp R1 to OU1 and Resp R2 to OU2 and R3 to OU3...etc.,
