Prerequisites
- Concept Authorization Objects and Fields An **authorization object** groups up to ten **authorization fields** that together define a specific access control check within an ABAP-based service, as described in [Authorization Basics](https://help.sap.com/docs/btp/sap-business-technology-platform/3461653ff5cc4cb1b13e578cadc412bb?locale=en-US&state=PRODUCTION&version=Cloud). Developers create authorization fields and authorization objects to protect a service by controlling what actions a user is permitted to perform on which data. Authorization fields can also be referenced when [creating restriction types](https://help.sap.com/docs/btp/sap-business-technology-platform/a800fb03751648d3bc70b8c70c26fbdd?locale=en-US&state=PRODUCTION&version=Cloud), which allow administrators to further refine access by combining restriction fields with authorization objects. Default values for these authorization checks are generated automatically and can be edited to adjust the permissions granted through business roles.
- Concept ABAP CDS Access Control The concept name was not provided, so a precise definition cannot be produced. Based on the available sources, the topic relates to implementing read protection in SAP BTP, ABAP Environment — a mechanism developers use to prevent unauthorized read access to data exposed by their applications. Developers define and enforce authorization checks so that only users with the appropriate permissions can retrieve sensitive data. For more details, see the [SAP BTP documentation on implementing a read protection](https://help.sap.com/docs/btp/sap-business-technology-platform/2a5524a8e57c4888a7ebec4898272484?locale=en-US&state=PRODUCTION&version=Cloud).
