What is a structural authorisation in SAP HR Security?

A structural authorisation is an object that defines the population that a user can access. Structural authorisations can be used to define a part of the organisational structure that a user gets access to.

Structural authorisations are configured in transaction OOSB.

In SAP 4.7 upwards structural authorisations can be combined with standard HR authorisations to create context sensitive authorisations using object P_ORGINCON.
