Ok so here's an example of how to mass generate PDF's from PO placed on various Vendors. The entire code, if used on a VBA for Excel, does the task.
Can the VBA coding in SAP be edited so that instead of generating PDF's, it can be used to change Delivery and Stat date for a certain line item and save the PO? Like a mass Date Conversion on PO? Because thats very tedious task to accomplish sometimes.
