One goal: leave this page genuinely understanding the access model, not memorising steps. We start with why access control exists, then the one big idea everything is built on, then the seven scopes one by one with workplace examples, and we close with denials, separation of duties, and delegation.
There is no such thing as "Mona can read salaries", full stop. The question always completes: read whose salaries? Her own? Her team's? Her company's? Everyone's? So every grant has two halves: the action (what is allowed — "read employees", "approve leave") and the scope (over whom). The Add-permission dialog shows exactly these two: the permission catalogue on top, the scope picker beneath it. An action without a scope is meaningless and the system won't accept one.
Scopes never widen by themselves — someone needing two scopes is granted both, explicitly. And the population scopes are derived from the org chart at the moment of the check, never stored: move an employee and the old manager stops seeing them while the new manager starts, within seconds, with no admin action.
Open the person in access administration → Add permission → search the action → pick the scope → write the reason → save; optionally set an expiry so the grant dies by itself. For recurring jobs use roles — pre-built bundles like "HR officer" — and keep individual grants for exceptions.
A denial beats every role, grant and delegation, instantly — the emergency brake when someone must be stopped without hunting where the access came from. And some permission pairs refuse to combine at all: whoever prepares a payroll run cannot also release it. Holding both blocks the action with a message naming the conflict — the simplest guarantee against both error and fraud, applied to humans and automated jobs alike.
Travelling? Delegate your approvals: pick what, pick the dates (expiry is mandatory), and the colleague must accept before anything happens. Everything they do is recorded in their own name marked "on behalf of you". Crucially, the scopes resolve from your seat: delegated "approve leave for direct reports" means your reports, never theirs. And a delegate cannot re-delegate. Cancel any time; it stops immediately.
