customer setup for EDI

First let me say that I'm new to JDE so any insight can be helpful and will be appreciated.  We're in the early stages of setting up our Electronic Data Interchange where we create the x12 document and send it to a third party to translate and send it to our vendors, customers, etc.  My question is what would need to be setup or designated in the customer master file to show that the record is set for EDI?

Thanks!
