Steps to Combine Detail LinesThe Combine Detail Lines option is used in Accounts Payable with requisitions that were converted to purchase orders to merge multiple detail lines that are similar to be just one line on the purchase order. For example, if several teachers each entered separate requisitions for whiteboard markers and the requisitions were converted to a single purchase order, there would be multiple lines for the same item (whiteboard markers); by completing the Combine Detail Lines option, the particular detail lines for the whiteboard markers could be combined together so there was just one line for the markers on the purchase order for the total to be ordered for all the teachers.
