Global Dat a Types: Bu i ld ing Bloc k s for In t er fac es

Global Data Types (GDTs) are:

Based on the International Standard UN/CEFACT CCTS (Core

Component Technical Specification)*

SAP-wide approved with reference to the Governance Process forProcess Integration Content (embedded within the SAP Standard

Application Integration and Interfaces)

Defined in the central Integration Repository using XML Schema

Well-documented according to the Document template Semantic building blocks for interfaces (reuse)

* UN/CEFACT CCTS is a methodology for developing a common set of semantic

building blocks that represent the general types of business data in use today

Global Data Types are company-wide defined data types with business

content, as found in standards or should be found in standards or

which are structured in accordance with standards

The Enterprise Services Browser allows you to browse the

business objects and service interfaces in the ESR and

generate proxies for these objects. The WSDL descriptions of

the objects are retrieved from the ESR and form the basis for

the generated proxies (outside-in programming model).

Service-based development can start right now!

SAP ESA is based in Web service technology

Enterprise services provide business functionality

Service-enabling is a focus area in the SAP ESA

SAP NetWeaver Exchange Infrastructure (SAP NetWeaver XI) is

the foundation of the ESR

There are two ways of developing service meta data: The inside-out and the outside-in approaches

UIBBs are standardized components for creating user interfaces.

Instead of programming the UI, you configure UIBBs using SAP

NetWeaver Visual Composer.
