Create vendor contact person
From Protemos Wiki
If the vendor is a Company you can add a contact person on the Contact persons tab of the vendor profile by pressing the "New contact person" button (this tab is missing in Freelancers and In-house employees profiles):
It will display the New contact person page where you can create the vendor's contact person. Just fill in the fields and press "Save" to confirm the entry:
Selected "Active" checkbox means that this contact person is still working for the vendor company and available for the contact.
You'll be able to select this contact person for your jobs. If you want to make this person disappear from the drop-down lists, please deselect this checkbox.
