I have a case where the client wants to know if there a way to catch or flag and account number that does not have daily activity. In the table below you can see that the account had some activity on the 09/01 – 09/04 and then again had some activity on the 09/15 – 09/18. So basically from 09/05-09/14 there was no activity and the clients wants to know how she can create a flag or an indicator that will let her know what this account does not...
