Review comment:
       @percyashu ..Maybe remove this exception? and put it back in the default case inside the } on line 91 above?
   
   Also if you want to add a default step, you need to check the `ReportRunFrequency.fromId(adhoc.getReportRunFrequency()` method from line 70 above and see how many different cases needs to be treated, then try to handle them all. Do we absolutely need a default case in all implementations of Switch statement?
   As seen here: https://errorprone.info/bugpattern/UnnecessaryDefaultInEnumSwitch, dont put a default statement if all the cases have been handled. Maybe skip it? Will that throw an error?
   
   Or given that ReportRunFrequency is an enum and we/Fineract is already handling all the 5 cases here, we can just throw a `new AdHocScheduledJobFrequencyException()` error here as default case with a message like "Correct Frequency not specified, Check the API docs"... @vorburger  @ptuomola your take?
