eXchange Integrator centers around the concept of a transaction profile for each trading partner relationship. Transaction profile information is stored on an LDAP-compliant directory server (usually called an LDAP server) through the following workflow:
Metadata for a transaction profile is defined in Enterprise Designer in the B2B Host.
Connecting the B2B Host to LDAP and building the B2B Host creates an eXchangeService and causes the metadata to be stored on LDAP.
Connecting the ePM GUI application to LDAP and building/deploying the application allows eXchange Partner Manager (ePM) to communicate with LDAP.
Values are eventually supplied using the eXchange Partner Manager (ePM) GUI, and activation of the trading partner produces transaction profiles stored on LDAP.
