This video is an introduction on building joined reports. It explains the process for selecting the different report types that have a common object to combine them into one joined report. The video shows changing the report format to joined format, the multiple block date field and time ranges, adding grouping to desired fields, and creating a cross block formula. The main focus is on explaining the options of adjusting the multiple date fields and time ranges on the different blocks that exist within a joined report and the effect those chosen fields could have within the overall report.
