Vendor Management

Good day all,

I have two questions related to vendor management:

First, we need a solution that allows our AP Manager to easily place vendors on hold across companies, let's say we have the following:

We created the vendor in company VND (which is where we create all our vendors) and then copied the vendor record to companies USA and CAN, thus retaining the same Party ID  for all of them.

If for some reason we need to stop purchasing or paying that vendor enterprise-wide, we want to be able to place all those accounts on hold at once... is there a way to do that?

And a second question is, what does the disallowed vendor form does?

Thanks all!
