I have a requirement to add people relationship with Assets

Assets and People information is coming from 3rd party application, we are receiving the all the data in the custom staging form, then I am pushing the all the fields to the BMC.Core forms but the question is

In which forms or form if I push the People information and Asset details it will build a relationship?

Note: I want to create relationship such as Owned by or Approved by which is visible in the AST: forms in the people tab
