To specify a report style:
(Optional) In the Title field, type a title for your report. This title will display in the margin area of the report.
Choose one of the report styles.
If you are basing your report on an Express query, you typically should choose a matrix or matrix with group report style.
If you change the report style of an existing report, Reports Builder will attempt to preserve your summaries in the new report style. If you are switching between report styles that require different data models (for example, Tabular to Matrix), though, Reports Builder may not be able to exactly map your existing summaries to the new report style.
