Hi

We originally imported our assets from CSV files, during this process some assets inadvertently listed the manufacturer as vendor.

Now, when using the purchase order module when trying to select a vendor for a new PO it auto populates the vendors from existing assets.

I have manually created a list of vendors we actually order IT equipment from however the vendor list is full of unused vendors. 

What is the best way to remove these unused vendors from the PO vendor drop down list?

Trying to delete the vendors from the admin section just throws up the error 'FAILURE :Vendor is being used by a module. Hence cannot delete it'

Any help would be appreciated.
