# Group audits

On this screen and the linked settings, users can set up a consolidated audit with audit units, materiality per component and linked audits. Within Engyon, it is possible to set up group audits, as required in [Standard 600](https://www.nba.nl/wet--en-regelgeving/hra/1619/1645/5184/5185/). In this chapter, you will read how this works. The following topics are described:

1. [Audit units](/engyon/en/reference/group-audits/audit-units.md)
2. [Allocate materiality to components](/engyon/en/reference/group-audits/assign-materiality-to-components.md)
3. [Link audit](/engyon/en/reference/group-audits/linking-audits-and-procedure-steps.md)
4. [Complex structures ('Christmas tree structures')](/engyon/en/reference/group-audits/complex-structures-tree-structures.md)
