Formula with set expression

[TomBond77]

Hi experts

My KPI BU-1 is not working, there seems to be a resolving problem of YYYY-MMM. For BU-1 I get this information: 

For BU-2 the same:

KPI: BU-1

Sum({<[Timestamp.autoCalendar.YearMonth]=
{"$(= date(Max(Timestamp.autoCalendar.YearMonth), 'YYYY-MMM'))))"}>} Sales))

KPI: BU-2

Sum({<[Timestamp.autoCalendar.YearMonth]=
{"2023-Nov"}>} Sales))

Where is the error in Formula for KPI BU-1?

Thanks, tom

Notice the quotes and braces are not in the correct positions in BU-1 as shown in the editor preview.
