Assigning Services 

Use

You use this function to assign services to the application components of integration scenario.

The type of service to be assigned depends on how you defined the application component when you designed integration scenario.

In the following, application components of type External Party with B2B Communication are B2B Components.

Application components that are not B2B components are Internal Application Components.

Relationship Between Application Component and Service Type

Application Component	Assignable Service
Internal application component (without assigned integration process)	One or more business system services One or more business services (only if the application component has at least one connection to a B2B component; in this case, the assignments between the business services and business system services must match)
Internal application component (with assigned integration process)	Exactly one integration process service Exactly one business services (only if the application component has at least one connection to a B2B component; in this case, the assignment between the business services and integration process services must match)
B2B Component	One or more business services

If an internal application component has at least one connection to a B2B component, use business services as neutral representatives for communication with the external party. The assignments between business services and business system services, and between business services and integration process services define which business systems or integration processes from your internal system landscape are mapped to which (externally visible) business services: this results in an appropriate header mapping in the receiver agreement that is generated.
