# Receiving Inspection

When a new lot of raw material or coating ingredient arrives at CoreForge, the warehouse verifies the supplier's paperwork before the material goes to production.

The `Receiving Inspection` check sheet is still started by hand and needs no sign-off, but it now requires an **item**, so every inspection is tied to the material that was received. Its check items are typed fields rather than pass/fail buttons: a supplier pick list, a validated lot number, a date and an optional photo.

In this section you will:

- Organize check sheets into folders and require an item from the raw material class.
- Build check items with different data types, instructions and regex validation.
- Complete the check on desktop and on the Kanoa Mobile app.
- Revise a released check sheet, and correct a check that has already been approved.
