Extracts:
Extract 1 - The
idea behind ALE is to provide a more rigid integration service while allowing a
high degree of independence to the individual SAP components. ALE also needs to
ensure consistency and integrity of data during the exchange of business
information across SAP and non-SAP systems. Applications are integrated by using
synchronous and asynchronous communication without implementing a central
database.
Extract 2 - We
will now proceed with the configuration methodology for ALE implementation. The
configuration is a multi-step approach. The steps can be categorized as follows
(as depicted in figure 5):
Extract 3 -
Listings are special filter object
types, which are used to specify a selection criterion for distributing master
data. Listings are based on the SAP Classification system. Lists are allocated
to an LS using transaction SALE (from the ALE customizing guide) or Distribution
Scenarios > Master Data Distribution > Distribution via Listings
Other
concepts covered in this paper include: Logical Systems (LS), Message Types,
IDOC, ALE Converter, Listings, Ports, Change Pointer.
