Report bursting allows a shared report to become separate outputs for customers, branches, departments or individual users. Produce PDF documents, Excel workbooks and CSV files where supported. Use Excel templates and formatting, merge suitable exports into workbook tabs, or collect several reports into a single email, ZIP archive or bookmarked PDF. Passwords and encryption help protect PDF documents. Route finished files to email addresses, Teams, SharePoint, OneDrive, Google Drive, Dropbox, FTP or SFTP servers, network folders, Slack and printers. Deliver exported documents to external audiences without requiring them to access Power BI. Execution records, notifications, retry settings and blank-report handling support unattended operation.
