Information Broadcasting in the Web (SAP Library - Security Guide for SAP NetWeaver BI)

Information Broadcasting in the Web

Direct distribution or setting of scheduling for background processing of BEx Web applications can be done in the Web using the BEx Broadcaster.

The BEx Broadcaster is a special BI Web item that behaves like a normal BEx Web Application and runs within BI. There is input help for selecting a Knowledge Management folder for storing the precalculated documents. This is realized as a portal iView (com.sap.ip.bi.portalnavigation.folderselection).

Three different scenarios can be classified:

1. BEx Broadcaster Is Called Directly in the Web Browser

If the BEx Broadcaster is called directly in the Web browser, an authentication at the BI system needs to take place. When calling the input help for the KM folder, a second authentication with the portal needs to take place.

Overview

BEx Broadcaster (explicit authentication at BI, Web browser receives BI ticket)

Input help (explicit authentication at the portal because the portal does not accept a BI ticket)

2. BEx Broadcaster Is Called Within the Portal

If the BEx Broadcaster is called from within the portal, authentication takes place implicitly with the BI system if the appropriate Single Sign-On has been set up between the portal and BW (see Calling BEx Web Applications from the Portal).

Overview

Portal (explicit authentication at the portal; Web browser receives portal ticket)

BEx Broadcaster (implicit authentication at BI with portal ticket)

Input help (implicit authentication at the portal with portal ticket)

3. The Settings Described in Publishing in the Portal Have Been Made

If the settings have been made, the portal accepts tickets from the BI system. Then the explicit authentication at the portal (described under point 1) that occurs when calling the input help does not apply.

Multiple portals can be connected to a BI system. See SAP Customizing Implementation Guide ® SAP NetWeaver ® Business Intelligence ® Reporting-relevant Settings ® BEx Web ® Integration into the Portal ® Maintaining Portal-Server Settings for the Portal. The portal that is designated as the standard portal is used when the input help for the KM folder is called.
