SAP NetWeaver Gateway Configuration Guide

 

Once you have installed the SAP NetWeaver Gateway components, you must configure your system to allow the consumer servers’ applications to retrieve the data requested by users.

The SAP NetWeaver Gateway Configuration Guide contains the steps for customizing settings for SAP NetWeaver Gateway and describes system configuration activities.

The sequence of mandatory and optional configuration tasks is as follows and depends on your use case.

Implementation Guide

The SAP NetWeaver Gateway specific configuration tasks are included in the SAP NetWeaver Gateway Implementation Guide (IMG) which is available in the system: In your SAP NetWeaver Gateway hub system (IW_FND) go to transaction SPRO, open the SAP Reference IMG and navigate to:   SAP NetWeaver  Gateway  . In your backend system (IW_BEP) go to transaction SPRO, open the SAP Reference IMG and navigate to:   SAP NetWeaver  Gateway Service Enablement  .

For all steps in the IMG there is always consumer-independent documentation available. If you want to see more information, select the Display icon before executing each step.

Note Note

If you have software components GW_CORE 190 and IW_FND 240 installed in your system, the IMG tree will only offer the activities for OData Channel.

The same applies if you use SAP NetWeaver Gateway in SAP NetWeaver 7.40 (software component SAP_GWFND).

For more information, see Deployment Options.

End of the note.

Recommendation Recommendation

We strongly recommend using the OData Channel (ODC) programming paradigm for all SAP NetWeaver Gateway development.

As of SAP NetWeaver Gateway 2.0 Support Package 05, you are strongly recommended to use the Service Builder (transaction SEGW) for your OData design-time development . For more information, see SAP NetWeaver Gateway Service Builder.

Depending on whether you want to develop SAP NetWeaver Gateway content in an SAP Business Suite backend system or in an SAP NetWeaver Gateway hub system, you can choose between embedded deployment or central hub deployment. For more information, see Embedded Versus Hub Deployment and Deployment Options.

End of the recommendation.

As such, several sections in the Implementation Guide (IMG) are merely available for reference and maintenance purposes.

  • In the backend system this is the section in the SAP Reference IMG under   SAP NetWeaver  Gateway Service Enablement  Generic Channel  .

  • In the SAP NetWeaver Gateway hub system these are the sections in the SAP Reference IMG under   SAP NetWeaver  Gateway  Former Development  .

Additional Software Components

Depending on the additional SAP NetWeaver Gateway components you implement, further component-specific configuration steps are required:

Business Enablement Provisioning (IW_BEP)

See Connection Settings for OData Channel and BEP and Backend Event Publisher (BEP) Configuration.

The IW_BEP specific configuration tasks are included in the Gateway Service Enablement Implementation Guide (IMG) which is available in the system: In transaction SPRO open the SAP Reference IMG and navigate to:   SAP NetWeaver  Gateway Service Enablement  Backend OData Channel  Connection Settings to SAP NetWeaver Gateway   and Backend Event Publisher Administration.

Screen Scraping (IW_SCS)

For Screen Scraping you only need to configure roles based on certain authorization templates. The templates specify the authorizations for content that can be accessed by the users and activities for developers. For more information, see Setting Up User and Administrator Authorizations.

SAP NetWeaver Gateway with HANA (IW_HDB)

If you want to install the SAP NetWeaver Gateway with HANA component (IW_HDB), this requires SAP NetWeaver 7.02 SPS09 comprising an ABAP Database Connectivity (ADBC) installation. ADBC is an object-based ABAP API for programming relational database accesses. It follows the Java Database Connectivity (JDBC) diction in its class and model structure.

Workflow

You can find more information about the Workflow-related configuration activities in Configuring Workflow for SAP NetWeaver Gateway. In addition, the relevant IMG activities are available in the Implementation Guide in the backend system: In transaction SPRO open the SAP Reference IMG and navigate to:   SAP NetWeaver  Gateway Service Enablement  Content  Workflow Settings  .

Business Process Enablement

For the special services provided within Business Process Enablement, such as Process Service and Process Context Service, the relevant IMG activities are available in the Implementation Guide in the backend system. In transaction SPRO open the SAP Reference IMG and navigate to:   SAP NetWeaver  Gateway Service Enablement  Content  Business Process Enablement  .

Consumer Settings

For information on configuration settings which need to be carried out for the different consumer scenarios and applications, see Configuration Settings for SAP NetWeaver Gateway Supported Scenarios.
