Report studio New features• Drill-up / drill-down.• Layout components can now be shared between reports.• Conditional Rendering of Objects in Reports• New ‘Member summary’ and Report functions• Creation of Query Studio Template• Maps• New Chart types added
Drill behavior enabled in Charts Baselines, markers and notes.
• Class styles• Crosstab Nodes and Crosstab Node Members• Disconnected or disjoint crosstabs, or crosstabs with unrelated
columns.• Page sets
Report Studio Overview• Reports
– BI reports • Lists• Crosstabs• Charts• Repeater• Maps
– Complex Reports• Multi-Frame• Drill up/down, through• Freeform Layout• Multi-Page
List Reports
• Headers and footers– List header
• Once for each occurrence of the list– Ex. on each page
– Overall header• Once for the entire list
– Group header(s)– Group footer(s)– Overall footer– List footer
List report shows data in rows and columns. It is used to show detailed information. The layout options available in a list report are
Crosstab ReportsCrosstab reports are used to show information in a more compact form than in a grouped list. Crosstabs are composed of edges
- Row edge defines the members listed on the left side of the crosstab- Column edge defines the members listed at the top of the crosstab- Cells contain the measure values
Edges are composed of:Crosstab Node: a collection of Node Members and
Nested NodesCrosstab Node Member: a collection of data items
that define members
Measures are also valid parts of an edge.
Crosstab ReportsDefault measure:
- the measure used when the row/column edge does not define one
- dropping a measure into the cells will set the default measure
- Report Studio shows the default measure name in the crosstab corner
Crosstab Reports
There are distinct drop zones within the crosstab allowing you to create very complex reports very easily.
- We use this drop zone to create child objects.
- And this drop zone to create peer objects –unions.
- Every cell has 4 Drop Zones –one on each side, one on the top, and one on the bottom.
Crosstab ReportsUse drag and drop to create many different Crosstab layouts using the Drop Zones Feature
Crosstab ReportsCrosstab reports features are as follows:
•Multiple measures•Nested rows or columns•Multi Grain•Drill Up/Down , Drill Through•Free Form layout•Conditional rendering•Maps•Totals at groups
• Row or column
ChartsCharts are a graphical way of representing data. They reveal trends and relationships that are not evident in tabular reports.There are over 100 chart types and chart sub-types available
•Column charts •Bar charts •Pareto •Line •Pie •Area •Point •Radial •Progressive Column•Progressive Bar•Gauge•Maps•Scatter, Bubble
ChartsOne can define drill up or down or drill through from elements in a chart.
Charts can be enhanced by applying informational overlays such as baselines, markers, and notes.
Maps
Use Map Manager to design your own maps.
Maps are defined by layers:
Region - color code areas on the map to compare values such as World, Country, or State
Point - color or size to map to compare values for cities, plants, sale districts
Display - show additional map details to provide context to the reader such as grids and/or an ocean Maps
Query• Tabular, Summary and Cube elements are no longer there.
• Has more simplified structure than in the earlier version.
• The Query model supports both RDBMS and OLAP data. It also supports Multi-Dimensional Expressions.
• One can have both a metadata (dimension/hierarchy/level) based and member based views of the dimensional data
• Joining queries (not Tables), Set Operations on Queries are defined in Query Explorer.
Query
Filters
• Detail filters
• Summary filters
• Slicers - In a crosstab, a slicer is a filter that is applied to the cells of the
crosstab, but not the rows or columns. - A slicer is a set of slicer member sets. Each slicer member set is an
expression that returns a set of members from the same dimension. - multiple slicer member sets can not be created against the same
dimension. - a child member of a report item can be added as a slicer.
Prompts
Prompts are user interface controls to request user input.
The features of prompts are as follows:
• Used for parameters in filters and calculations
• Optional and required
• Single and multiple values
• Multilingual
• Report Studio will default prompt type
Prompt Types
• Text Box Prompt
• Value Prompt
• Select & Search prompt• Date prompt• Time prompt• Date/Time prompt• Interval prompt• Generated Prompt
The different layout objects available to create a report are:
•Table•Block•Text•List•Crosstab•Chart•Map•Repeater
•Bookmark •Html•Image•Hyperlink•Calculation•Filters•Prompt
Layout Objects
Conditional Processing
• Conditional highlighting based on variables
• Conditional text based on multilingual variables
• Conditional Blocks
• Conditional Rendering:
• object not rendered based on variable
• as if the object does not exist (versus exists but transparent or hidden)
• most useful to hide a column in a list
• supported on:
• Block, Text item, List, List column, Crosstab, Chart, Table, Repeater, Repeater Table, Repeater Table Cell, image, hyperlink, hyperlink button, prompts, HTML item, field set, and so on.
Shared Layout Components
Report Studio’s use of Shared Layout Components:
• The layout components can be shared across reports
• The layout component can be updated at run-time or design time:• Each time the report is run it fetches the latest page header and
uses it• Update the page header only when the Report Studio user elects to
do so• Layout Component Cache
