Purchase Orders by default do not require a vendor number. No No vendor may mean the user just hasn't assigned one yet or that it will be used as a 'multi-vendor' purchaser order. Multipurchase order (non-vendor specific). Multi-vendors are no longer used.
A vendor may be entered at any time prior to entering the first invoice. If a vendor is not entered prior to the first invoice, it will be assumed to be a non-vendor specific (i.e.,multi-vendor) purchase order and the vendor will need to be entered at invoicing time. In this case, once an invoice has been processed against the purchase order, it will no longer be possible to enter a vendor on the purchase order.
Individual user purchase order processing is controlled by a variety of variables, such as User account where the Account Filter and Role (and the Permissions assigned to those Roles) are defined for each user, User Preferences, Rules, etc. By default the system will give a warning if the budget's remaining balance will go negative. Remaining balance is either unencumbered balance or unencumbered balance - outstanding requisitions depending on whether the pre-encumbrance module is enabled and the specific rule(s) the district has enabled.
