Information Broadcasting in the Web
You can use BEx Broadcaster to distribute or set the scheduling for background processing of BEx Web applications directly in the Web.
BEx Broadcaster is a special Web item that behaves like a normal BEx Web application and runs in SAP BEx. Input help is provided for selecting a Knowledge Management folder to store the precalculated documents. This is implemented as a portal iView (com.sap.ip.bi.portalnavigation.folderselection).
There are three different scenarios:
1. BEx Broadcaster is Called Directly in the Web Browser
If BEx Broadcaster is called directly in the Web browser, authentication is required in the BW system. When the input help is called for the KM folder, a second authentication is required in the portal.

BEx Broadcaster (explicit authentication in BW, Web browser receives BW ticket) |

Input help (explicit authentication in the portal because the portal does not accept a BW ticket) |
2. BEx Broadcaster is Called in the Portal
If BEx Broadcaster is called in the portal, authentication takes place implicitly with the BW system if the appropriate Single Sign-On has been set up between the portal and BI (see Calling BEx Web Applications from the Portal).

Input help (implicit authentication at the portal with portal ticket) |
3. The settings described in Publshing to the Enterprise Portal
If the settings have been made, the portal accepts tickets from the BW system. There then no explicit authentication in the portal (described under point 1) when you call input help.

Multiple portals can be connected to a BW system. See SAP Customizing Implementation Guide → SAP NetWeaver → SAP Business Warehouse → Settings for Reporting and Analysis → BEx Web → Integration into the Portal → Maintain 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.
