In Simple English, Not is being used to show the negative meaning of the context. In Web Intelligence, "Not"" is also projected as same but still we can use for reverse logic. Syntax of Not Function: Not(Object) – It returns boolean value. For example, consider a below condition. If “Status” = “Approved” then “Process Completed” else “Waiting.” If “Status”<>”Approved” then “Waiting” else “Process Completed.” We can use NOT function for the second condition. It would be like below, If NOT(“Status”=”Approved”) then “Waiting” else “Process Completed.” When we see "Not" function alone, then it would be simple, but when "Not" function is combine with other functions, then we can handle the complex logic very quickly.
