Such customized reports may be applied for calculation contacts, accounts, leads, opportunities, campaigns, orders, contracts and activities. Let’s figure how to make it for Contacts & Accounts. You need to select this report type from a drop down menu and click on the “Create” button.
In the Show you select All Accounts from a drop-down menu. In the Data Field you pick up Create Date from a drop-down menu. And in the Range choose All the time and click on ‘Run Report‘ button.
When the process of report running is complete, you see all related information and the total number of records.
