Hi Hao,
Yes that is correct.
Account and Contact is 1:N
Contact and custom entity is 1:N
I am struggling to build the relationship between the Account and the custom entity. You are correct in saying that it should be:
Account and custom entity is 1:N
For example:
A university (account) can have many students (Contacts)
A student (Contact) can have any qualifications (Custom Entity linked to Contact)
But I'm struggling to formulate a relationship in which I can report on the number of qualifications that the university has issued.
Account linked to multiple custom entities.
