Defaults and Overrides

ePM allows you to override the default parameter properties at any component level except the top-level B2B Host. Overrides inherit from “parent” to “child” components. Default overrides cascade from B2B Hosts to TPs by way of Action Groups. You can also configure specific overrides for individual TPs.

For information on Lookup parameters and how they operate in ePM, including how they are inherited and overridden, see the eXchange Integrator User’s Guide.

The current TP configuration inherits the current B2B Host configuration. Additionally, ePM allows you to override any inherited parameter values at this level or at any lower level in the TP, if necessary. See Figure 4–1.

For example, a TP’s Action Group overrides are inherited from the current B2B Host’s Action Groups.

Because Transaction Profiles are assigned to TPs (by way of Action Groups), any inherited parameter defaults and overrides may be additionally overridden at this level. This feature allows you to effectively “customize” a Transaction Profile for a specific TP.
