Ans :Sales force Report Types
1. Tabular reports Simple Excel type tables which provide a list of items with the grand total.
2. Summary reports Similar to Tabular reports, but also have functionality of grouping rows, viewing subtotals & creating charts.
3. Matrix reports Two-dimensional reports which allow you to group records both by row and column.
4. Joined reports Multiple blocks showing data from different reports based on same or different report types.
Another important point to note here is that, only Summary reports and Matrix reports can be fed as data source for dashboards. Tabular and Joined reports cannot be used as data source for dashboards.
