## In this section

- [Limits at a Glance](https://help.rikaiso.com/public-cloud/2026.2/limits.md): Every number users rely on, in one table: file size, rows, columns, template records, findings, time windows, retention periods and the quota notice.
- [Keyboard Operation and Accessibility](https://help.rikaiso.com/public-cloud/2026.2/keyboard-and-accessibility.md): How to operate every app with the keyboard, the screen-reader announcements, and the accessibility standard MDM is tested against.
- [Notification Events](https://help.rikaiso.com/public-cloud/2026.2/notification-events.md): The event types, severities and tags MDM sends to your SAP Alert Notification service for finished jobs.
- [Data MDM Stores](https://help.rikaiso.com/public-cloud/2026.2/data-stored.md): Per store: what MDM keeps, why, for how long, who can see it and how it is deleted.
- [SAP Documentation Referenced](https://help.rikaiso.com/public-cloud/2026.2/sap-references.md): The SAP Help Portal and SAP Business Accelerator Hub pages behind every API and rule, so you can read SAP's own words.
