Card 1 of 10

A retail company needs to track Orders and Order Line Items. Order Lines must always belong to an Order and should be deleted when the Order is deleted. However, the security team says Order Line sharing must be independent from Order sharing because warehouse staff need Line Item access without seeing Order financials. Lookup or Master-Detail?

Use Lookup relationship, not Master-Detail. While MD gives you cascade delete and roll-up summaries, it also forces sharing inheritance — child records always inherit the parent's sharing. Since warehouse staff need independent access to Line Items without Order visibility, Lookup is required. Implement cascade delete via Apex trigger or Flow. Use Apex Aggregate queries or Flow to replicate roll-up summary functionality. Trade-off: you lose declarative roll-up summaries and must maintain custom deletion logic, but you gain independent sharing control. This is a textbook CTA trade-off question — always identify the constraint that forces the decision.
