I have a question on how to connect two fields. I have a a filed on custom record and another custom field on the Vendor bill. I need data from the field on the custom record to appear in the field on the Vendor bill. How do I do that (without a script please)?

I can think of 2 options: 1. You could use Workflows for it. 2. If the custom field is already referenced on the Vendor Bill, you could also use that to 'Source' data from in the custom field definition itself.

thanks, @Ankur Sanghi! on that note - can I use a Workflow to connect that field to the Amount field under Item?
