Use

SAP NetWeaver Portal provides different ways for consumers to use remote content exposed by SAP NetWeaver and non-SAP producers in a federated portal network. Each content usage mode is suited to a different use case, scenario, or system landscape. You can also combine modes.

This section presents the available content usage modes and discusses their technical aspects, advantages, and disadvantages.

For information about the relation of content usage modes to real-life business scenarios, visit the Federated Portal Network area on SAP Developer Network at http://www.sdn.sap.com/irj/sdn/nw-portalInformation published on SAP site.

Content Usage Mode

Description

remote role assignment

A user administrator on an SAP NetWeaver consumer portal assigns users directly to portal roles residing on a remote SAP NetWeaver producer portal. When a remote user accesses a remote role via the consumer portal, the runtime execution of the entire role structure and its applications is performed on the producer.

The main advantage of this mode is that content management, maintenance, and configuration on the consumer is kept to an absolute minimum-the entire role structure is defined and configured solely on the producer. A user administrator is sufficient to perform the remote role assignment.

For detailed information, see 'Remote Role Assignment' Mode .

remote delta link

A content administrator on an SAP NetWeaver consumer portal creates remote delta links to content (iViews, pages, worksets, or roles) residing on a remote SAP NetWeaver producer portal. The runtime execution of applications is performed on the producer.

The main advantage of this mode is that the remote delta link content is local and can be customized according to the needs of the consumer, while at the same time, changes made to source objects on the producer are automatically inherited by their target delta link objects on the consumer. Standard delta link behavior applies to remote delta links.

For detailed information, see 'Remote Delta Link' Mode .

WSRP application sharing

A content administrator on an SAP NetWeaver consumer portal integrates remote WSRP portlets/iViews exposed by a non-SAP or SAP NetWeaver producer portal as standard iViews in the consumer portal. The runtime execution of portlets is performed on the producer.

SAP NetWeaver Portal can also function as a producer and expose its iViews as portlets for use by other SAP or non-SAP consumer portals.

The main advantage of this mode is that it is based on WSRP technology built into SAP NetWeaver Portal, thus enabling portlet interoperability across different WSRP-compliant vendors.

For detailed information, see 'WSRP Application Sharing' Mode .

Figure: Content usage modes offered by SAP NetWeaver in a federated portal network. In the figure, each content usage mode depicts a source object on a producer portal that is created on a consumer portal at design time. The runtime execution of the consumer object takes place on the producer. Note that the figure shows remote usage of iViews only, while remote delta link supports additional objects types, such as roles, worksets and pages.

The following table summarizes which content usage modes are supported by the various SAP NetWeaver and non-SAP combinations of producers and consumers:

Non-SAP

(1) An SAP NetWeaver CE portal is qualified to function as a producer portal only. Consumer capabilities are not supported.

(2) WSRP application sharing used in SAP NetWeaver-to-NetWeaver interactions is applied differently to SAP NetWeaver-to-non-SAP interactions. These differences are covered in this guide.

(3) SAP documentation does not cover non-SAP to non-SAP portal interactions.
