The SAP ALE (Application Link Enabling) interface is part of the
integration layer within the SAP Business Framework Architecture (BFA). BFA
is a component-based architecture that enables business process integration
and asynchronous data communication between two or more SAP systems or between
SAP and external systems. Application systems are loosely coupled in an ALE
integrated system and the data is exchanged asynchronously.
The adapter interacts with the ALE interface to support outbound and inbound
processing by enabling the exchange of data in the form of business objects.
The data exchange includes the following activities:
- SAP Intermediate Document (IDoc) exchange for inbound and outbound events.
- The IDocs can be exchanged either as individual documents or in packets.
- From the SAP application, IDocs can be sent as parsed or unparsed documents.
- Transaction ID (TID) management for inbound and outbound events. The adapter
uses tRFC (transactional RFC) for inbound and outbound events to guarantee
delivery and to ensure that each IDoc is exchanged only once with SAP.
For inbound processing, the adapter is able to listen to and deliver events
from multiple SAP systems.
Adapter for SAP Software is also
able to deliver events to multiple SCA endpoints. You enable delivery to multiple
endpoints by configuring multiple activation specifications.
- If the endpoints subscribe to the same events from the same SAP system,
all properties in the individual activation specifications must be identical.
- Endpoints that subscribe to different activation specifications receive
events that match the criteria for the activation specification.
Define a separate activation specification for each endpoint to which events
need to be delivered, except when the adapter delivers events only to those
endpoints that are active.
