Profile substitution works for recurring event, if you choose aggregation period as "no aggregation"

Hello Sathees, Quick clarification your answer "seedmember can be extended with profile fields". Here in my case we are not extending the profile or profile extended attributes for Seedmember. We are trying to extend the custom schema for seedmember, which is a linked schema for profile.

just wanted to know Seedmember extension scope is with in the nms:recipient boundaries or it can be any other custom resource ?

Also i tried extending the seedmember schema and created a link with custom resource, but getting a publish error as "Unable to find XPath element 'recipient/customresource/@customres-attribute' in schema 'nms:recipient'."

included screen shots..

I have a similar requirement.
