WHY IT NEEDS A POLICY

Why quickfile_purchase_create needs a policy

Creating a purchase invoice in accounting software writes a new financial transaction record to the system. While reversible (can be deleted or cancelled), it modifies the financial state and creates an obligation record. This is more severe than a simple Read operation but less severe than Destructive (which would be irreversible deletion).
