We've created a custom object "Enquiry" in sales cloud which is child object of "Lead" object. (i.e. Lead represent a unique user)

We've also deployed marketing cloud which is in sync with sales cloud. I want to create a data extension which will be used to send emails on each enquiry. Can I create this data extension in a fashion such that primary key is Enquiry_Id and Lead_Id is mapped with SubscriberKey. (Context - Whenever I create a DE and make any field as Primary Key, Marketing cloud automatically maps primary key with subscriber key).

(Leads are being counted as Contacts in marketing cloud)

I've raised ticket to support for this and got the answer.

You can create a data extension where primary key is different and key which maps to subscriber is different.

For update purpose, primary key will be referred & for contact count, key which is mapped to subscriber key will be referred.
