BPC Measure to Display OPENING BALANCES

Trying to generate custom measure (PER_OPEN) to display previous month into current month .  and Month 1 into Q1  and Y.

Example :

i have copied periodic measure into PER_OPEN custom measure and changes CLOSINGPERIOD to OPENINGPERIOD  but values are not populated as per expected results. is there any work around about this ?

Thanks,

Satya.
