A Trading Partner Agreement (TPA) is a set of parameters that you can use to govern how business documents are exchanged between two trading partners. When you import a Chem eStandards Process Archive (.par file) into the webMethods Integration Server, the TPAs for that process archive are created in webMethods Trading Networks. You view and customize the TPAs using the Agreement Details screen in Trading Networks Console. For information about working with TPAs in the Trading Networks Console, see the webMethods Trading Networks Administrator’s Guide.

Every Chem eStandards conversation in the webMethods Chem eStandards Module is associated with two TPAs, one for the initiator/sender in a conversation and one for the fulfiller/receiver in a conversation. The TPAs provided with the webMethods Chem eStandards Module contain a set of parameters that map to some (but not all) elements in the Service Header of a business document.
