Abstract: Described are embodiments directed to providing a preview feature in a report designer that allows modifications to report metadata to be made and previewed accurately. In embodiments, the feature allows a user to open a report to make changes to metadata of the report and have an accurate preview of how the report will look when published on a report publishing server. Embodiments provide for a report publishing server to allocate an in memory location that stores modified metadata of a report. The in memory location allows relative paths and references to sub-reports or data sources in the original report to be accurately reflected in a preview on the client.
