On Sap B1 2005 when we made a Back-to-Back PO's from Sales Orders the Sales Order information stayed on the screen in the background and was very handy when doing a multiple line items as we put the list prices on non-printable text lines for future reference.
Now with 2007 the sales order information disappears and the only way to keep the information on the screen is to save the order without ticking the PO check box, then re-open it and then tick the PO check box.
Why would SAP do this?
