Regarding my business scenario have the following two lists,
1. Business Profile
2. Site Profile
One BusinessProfile can have more than one SIteProfile. When a user create the BusinessProfile, He able to create the SiteProfiles as well.
I have one idea. That is use a repeating section for SiteProfile in the BusinessProfile then after the form submit, Update the Repeating control data to SiteProfile List.
But I post this question for find any other method like in my question title?
