## Formula Help - That shows me the months available in format YYYYMM

Hi,

I would like to make a selection that lets me select a YYYYMM between 201701 and 201812 (Capture.PNG)

In my data I have a column for YEARMONTH starting with 201601 to 201812

This is the initial formula but it only shows me 201601 to 201612 and 201801 to 201812

=Concat({<YearMonth=-{'\$(Year)'}>}distinct YearMonth,',')

\$(Year) =year(today())-1&'*'

Can you help me understand the formula?

This will return like

YearMonth

201601

201602

201705

201801

201811

201811

Concat(DISTINCT YearMonth, ',') -- It ignores the duplicate values

201601, 201602, 201705, 201801, 201811

Your expression work as Concat({<YearMonth -= {'\$(Year)'}>} DISTINCT YearMonth, ',')

So, The variable year returns \$(Year) =year(today())-1&'*' ------ It displays last year data which wildcard function like 2017* -- Wildcard data loading (*.blah......)

Not sure I understand completely, would you be able to share a sample and show your issue?

As Anil pointed out, the variable is a match to all months in the current year

The expression is excluding everything in that match, so, 2016 and 2018 will be displayed and 2017 will be excluded.

## Re: Formula Help - That shows me the months available in format YYYYMM

YearMonth -= {'\$(Year)'}

so the '-' is excluding the values that are the same with last year

I think I get it now.

The formula is ok. But I need to change the \$YEAR formula....annnnnnd.... now it works!

Thank you guys for the help.

## Re: Formula Help - That shows me the months available in format YYYYMM

It's ok I understood the condition formula

=Concat({<YearMonth=-{'\$(Year)'}>}distinct YearMonth,',')

and the variable formula

\$(Year) =year(today())-1&'*'

And I changed it to show me the info from 201701  to 201812
