Currently when a Requisition is purchased using the PO Preview window similar line items automatically get combined into a single PO line. The process only looks at a few of the line item fields, such as Item number, site, unit cost, vendor and required date. Unfortunately line item descriptions and comments are not included in this check. Currently users modify the Item description on similar line items to provide information for the vendor. This information gets lost when it combines the lines. I would suggest either including these fields in the combining check or at a minimum provide a POP setup option to disable the combining of lines at a company level.
