EPMDimension Override using multiple property

HI People,

I have WBS Dimension in row axis and Cost centre & Company code are in Coloum axis.

And had Cost centre and Company Code as a property in WBS Dimension.

I am trying to override my WBS dimension using two properties (Cost centre and Company Code) and it is not working but it is working if i try to override using any one of single property?

Used formula : =EPMDimensionOverride("000","GII_WBSELE","COST_CENTER=C3 AND COMPANY_CODE=C4")

PS let me know if any was wrong?

Thanks,

Vishu
