Abstract: Revision of a part specification document, such as a drawing, a part specification, or a bill or materials, prompts execution of an automated notification process. A unique part number associated with the revised part specification document is employed in searching open purchasing documents for purchase orders or request for quotes containing the part number. Electronic mail addresses for outside supplier contacts are kept in the database and linked to the supplier master of the open purchasing documents containing the part number. An electronic mail notification of the part specification document revision is generated and transmitted to each electronic mail address identified as being associated with an open purchasing document containing the subject part number. The revision notification includes a link to the revised part specification document to enable the outside supplier to access the document and review the revisions.
