# AP Invoices

> Partial update AP Invoices in batch

**Security**

The requesting user must have one of the following permissions to approve AP invoices:

- Accounts Payable → AP Invoices → Approve AP Invoices
- Food → AP Invoices → Approve AP Invoices (Food equivalent)

Approve and create are separate permissions — this permission does not grant create rights.
