Managing a Vendor Entity can be easily done by following these few simple steps:
A Vendor is only selectable as a contact for assets, purchase orders, or work orders if they are active, assigned to the same entity, and have the right to be assigned.
Step 1.
Create a new Vendor or open an already existing Vendor from your desktop computer.
If creating a new Vendor, all required fields must be filled in and then saved before you can proceed to Step 2. If you need help on how to create a new vendor, see article, “How to Create a Vendor Manually.”
To learn how to delete an entity, go to Step 4.
Step 2.
Click on the Entities tab.
Step 3.
Use the drop-down menu entitled Entity to select which location you want to choose then click on 
Add Entity.
Once you have finished this step, you have successfully added a entity to your Vendor and are ready to proceed.
Step 4.
To delete an entity that has previously been added, click on the 
Delete button on the right-hand side of the screen.
Once you have finished this step, you have successfully deleted an entity from your Vendor and are ready to proceed.
