Departments must review all open encumbrances posted against their funds to determine if they remain legitimate expenses. Any that are not legitimate after payment, need to be closed by the campus purchasing office. To close out an encumbrance, please “Add Comment" to the PO with reasons for closing [Example: Please close Line 1, item has been discontinued.] Please checkmark the name of your purchasing officer in the comment area so he/she receives an email notification of your intent.
