The idea behind flags is to transfer calculations respectively parts of them from the gui into the script so that those informations exists already as native fields within the datamodel.

Quite common for it are period-matchings like YTD or LYTD - of course you could use set analysis or various if-loops within your gui-expressions to refer to these periods - but often it will be easier to define these periods within the script within a master-calendar and using then simplified expressions like this: sum(value) * Flag_YTD.

Beside simplifying things will be the performance with flags significantly better than with more complex conditions within the gui-expressions.
