I do have a Custom object: Information__c which is a child object of the Case. As we all know, Case is a Child object to the Account. Now I wanted to restrict(visible to) Informations to specific to each account.
So on the Community Sharing sets, I have had:
For the Object: Information>>
User:Account = Information:CaseLookUp__c.Account to Read Only. With this, any different Account user still see other Account's Information records.
My question: Can't we use sharing sets to TWO level lookups? If not, do I need to explicitly create a Lookup to Account on the Information object?
