How to set up query template

In Lumira, you don’t have to create separate dashboard for each query if it should look and work the same way. You can crate one dahsboard with one datasource and use following parameters:

XQUERY=technical_name_of_bw_query
XSYSTEM=cuid:olap_connection_cuid

Example: http://example.com:9999//BOE/OpenDocument/opendoc/openDocument.jsp?sIDType=CUID&iDocID=xji8HAJksao&XQUERY=ZBW_FI_Q001&XSYSTEM=cuid:jKIoa98a

Also a small entry in the startup script of the template is required:

DS_1.assignDataSource(XSYSTEM, DataSourceType.QUERY, XQUERY);
