Day 7 - How Hierarchy and External Lookup Relationships Work in Salesforce (Deep Dive)

Описание: In this video, we break down Hierarchy Relationship and External Lookup Relationship in Salesforce in a way that actually makes sense.

Here’s the thing. Most people memorize definitions. That fails in real projects and interviews. So in this session, we focus on how these relationships work in real life, not just what Salesforce documentation says.

You’ll learn:

• What a Hierarchy Relationship really is and why Salesforce restricts it to the User object
• Real-world use cases like manager reporting, approval flows, and role-based access
• How External Lookup Relationships work when data comes from an external system
• How Salesforce matches external records at runtime using unique external IDs
• What happens when a match is found vs when no match exists
• Differences between External Lookup and Indirect Lookup (clearly explained)
• Common mistakes developers make while designing external relationships
• Interview questions and scenarios you’ll actually face as a Salesforce Developer

We also discuss how Salesforce behaves behind the scenes when fetching external data, which is something most tutorials skip.

If you’re a Salesforce Admin, Developer, or preparing for interviews, this video will give you clarity that sticks.
