Assign Items to Vendors and Create Records for Unknown Vendors
If a technician purchased items from a vendor who is not already entered in the system, complete these steps.
You also need to complete step 2 if both the item and vendor already exist in the system, but the item is not assigned to the vendor from whom it was purchased.
In Microsoft Dynamics GP, select Cards > Purchasing > Vendor. In the Vendor Maintenance window, create a record for the vendor.
In Microsoft Dynamics GP, select Cards > Inventory > Vendors. In the Item Vendors Maintenance window, assign the item that was purchased to the vendor record that you just created.
