RunAllocation using property

Hi Gurus,

I'm on BPC 10 MS.

I need to use a runallocatioin  to save value stored in Account "A" and Business Unit "Dummy" using distribution of account "B" in Bas(Total Business Unit".

I need to use runallocation several times with different destinations and different drivers.

I've created a property "DRIVER_BU_BS" to get the correct driver for each account.

The logic is validated correctly but doesn't works.

I've attached the script logic

Could I use dimension property in runallocation ?

Thanks

S.B.
