When changing owner for an Account opens a pop up that says,
The new owner will also become the owner of these records related to Think Big Corp that are owned by you.
1. Open opportunities
2. Contracts in Draft and In Approval status
3. Orders in Draft status (with or without a transferring contract)
5. Notes and attachments
6. Open activities
If I change the owner of opportunities directly, it triggers the code I have written in Opportunity trigger. But when I change owner for Account it simply changes the owner of the opportunity without triggering the opportunity's trigger.
The same happens for Contacts too. Contact has a trigger code which updates the Individual's owner to the same owner of the associated Contact. But when I change owner for Account it simply changes the owner of the Contact but doesn't change the associated Indiviudal's owner to that of the new owner of Contact.
