System Member - TPDate creation gives error in PBCS while validating BSO Member formula

Hello All,

I have a query regarding System Member TP-Date (which is usually used in Capex for Date related calculations) in Hyperion Planning Application.To give a brief: I am trying to replicate Seeded Capex like functionality in PBCS(Cloud). I am able to create other such members like CalendarTPIndex, FiscalTPIndex, NumberOfPeriodsInYear, YearIndexes, FirstDate through BSO-Formulas as in on-premise Application but the same is giving error for TPDate.

The TPDate BSO-Formula i am trying to use is as below:

[OpenInputValueBlock] [TPDate] [CloseInputValueBlock]

with UDA: HSP_NOLINK

But i am getting below error on validating the same:

An error occurred while validating the member formula.
