BI SAP Query Connector A resource adapter for the Business Intelligence domain based on SAP Query, which is a component of SAP's Web Application Server that allows you to create custom reports without any ABAP programming knowledge. The BI SAP Query Connector uses SAP Query to allow applications created with the BI Java SDK to access data from these SAP operational applications. You can also use the BI SAP Query Connector to make these data sources available in BI, via BI's UD Connect. The SAP Query Connector implements the BI Java SDK's IBIRelational interface. BI XMLA Connector A resource adapter for the Business Intelligence domain based on Microsoft's XMLA (XML for Analysis), which facilitates Web services-based, platform-independent access to OLAP providers. The BI XMLA Connector may be deployed into SAP's Web Application Server, and enables the exchange of analytical data between a client application and a data provider working over the Web, using a SOAP-based XML communication API. The BI XMLA Connector allows you to connect applications built with the BI Java SDK to data sources such as Microsoft Analysis Services, Hyperion, MicroStrategy, MIS, and BW 3.x. You can also use the BI XMLA Connector to make these data sources available in BI, via BI's UD Connect. The BI XMLA Connector implements the BI Java SDK's IBIOlap interface. broadcast setting Collection of parameters that serve to distribute a query, a Web application or a workbook by e-mail or to the Enterprise Portal. A broadcast setting can be identified uniquely by a technical name. You can determine whether the broadcast setting is to be executed immediately or whether it is to be scheduled for a particular point in time. You can also determine that the broadcast setting is scheduled to be executed when changes to data in the underlying InfoProvider are made. broadcasting framework Technical infrastructure for BEx Information Broadcasting. 288 Best Practices for SAP BI using DB2 9 for z/OS
oadcasting wizard Assistant that supports you by giving step by step instructions on how to precalculate and distribute queries, Web templates or workbooks. With the broadcasting wizard you are able to create precalculated documents and online links and either distribute them by e-mail or publish them to the Enterprise Portal. You can also jump to the BEx Broadcaster in order to define further settings. Business Content Predefined role and task-related information models that can be suited to enterprise-specific requirements. Business Content makes the supply of information available to roles in an enterprise, that require this to complete tasks.
