We have a LOT of older Vendors we don't use anymore and I want to delete all those old vendors.

But whenever I click the trashcan on a Vendor under Admin -> Asset Management -> Vendor I consistently get the error "FAILURE :Vendor is being used by a module. Hence cannot delete it."

A suggestion: In these kinds of error messages, could you PLEASE write out WHAT module? "A module" doesn't help!

So how do I find the module it is being used by?

And how do I stop it being used by that module?

I have checked under the Vendor settings and it says:

Under Products: "No product associated with this vendor {0}"

Under Services: "No service associated with this vendor."

I really don't get why I cant delete the vendor! Please help!
