Give Technicians Access to Vendors
By default, vendors in Microsoft Dynamics GP are visible to technicians, who can select a vendor while creating a purchase order. You can designate which vendors the technicians can select if you do not want all vendors to be displayed in lookup lists.
In Microsoft Dynamics GP, select Inquiry > Service Management > Mobile Vendor Setup. The Mobile Vendor Setup window is displayed.
Unmark the checkbox next to vendors if you do not want the vendors to be displayed in lookup lists in MobileTech.
Select OK.
