The SAP NetWeaver Gateway Service Builder provides a tool for centrally defining and creating OData services. It allows modeling of entity sets, types and properties from various data sources. Services can be generated based on existing models from SAP applications like ERP, CRM, BW, HANA or custom models. The service builder supports code-based and declarative implementation approaches and registration of the services with the Gateway server.

SAP NetWeaver Gateway Service Builder
The SAP NetWeaver Gateway
Service Builder provides a tool to
centrally display and create the
definition of an OData Service.
 Runtime artifacts (model provider
class, data provider class, model
and service)
 OData artifacts (entity set, entity
type and properties)
 Used data sources and models
Models can be created based on
EDMX-Modeling.
The modeling environment follows
a project based approach, all
relevant data is consolidated in
this projects.

Step1:
Generate a “technical” service which calls the
BW
Step2
Beautification” of the external names
Example
 Generate services from existing business
objects from (for example)
 PLM and EAM
 CRM
 BW
 HANA

Service generation – SAP Business Warehouse
SAP NetWeaver Gateway
enables SAP BW content for
light weight consumption via
OData. This happens by
providing generators for
- Easy Query
- MultiDimensional
eXpresions (MDX)

Service generation – based on SAP HANA
Via the new SAP NetWeaver
Gateway with SAP HANA
integration capability it is now
possible to connect to SAP
HANA.
Currently only Read-Only access
is supported.
The following information models
can be exposed as an OData
Service:
 Attribute Views
 Analytic Views
 Calculation Views

Mashup Gateway services
Example
 To create a sales order you need two types
of master data “Customer” and “Products”.
Reuse of existing Gateway services for
 Customer and
 Products
 Leverage analytical read-only services from
BW and Hana in CRUD-style service
