Dynamics GP Tip of the Month: Easy edits with vendor and customer modifier and combiner
Have you ever discovered weeks after setting up a new vendor in Microsoft Dynamics GP (Great Plains) that you’d accidentally created a duplicate under a different vendor ID? Or maybe a customer changed their name and you want the customer ID to reflect that update accurately? These scenarios are all too common, and correcting them could mean tedious manual updates or costly third-party tools.
