Edit: Never mind I just saw the "-99".

Also a way to do it. Personally I would prefer going for encapsulated out-of-the-box functionality which can be used by all users in exactly the same fashion and doesn't need to be reproduced for each use case.

I would adapt the filter as "functionally" it has a mistake:

"Time"."Month Short Name" >= (@{pv_MonthShortName-99}{201801}) AND "Time"."Month Short Name" <= (@{pv_MonthShortName}{201901})

=> if no variable it will return 13 months and not 12

For better readability and chances somebody will understand what's going on in the future the '-99' would need to be outside of the variable to keep the logic coherent between default values and variable:

"Time"."Month Short Name" >= (@{pv_MonthShortName}{201901} - 99) AND "Time"."Month Short Name" <= @{pv_MonthShortName}{201901}

(a BETWEEN can also be used instead of 2 filters)

The logic of this approach is purely mathematical: by expressing months as 6 digits YYYYMM the -99 act as "go back 1 year and forward 1 month" (-100 + 1).

Because of the numerical implementation the border case of December still works ( YYYYMM BETWEEN 201713 AND 201812 when selecting December 2018).

It works, sure, as long as nobody asks to see months in a different format in the prompt (like "Jan 2019" or things like that). There are various other implementation for that kind of "period rolling" requirement.
