Validate BPC data with ECC data

Hi Experts

We load data daily from ECC -> BW -> BPC

Now user wants to verify that data in BPC and ECC are sync ( using some automatic process - not drillthrough ) after each load.

ex: Data loaded for Month - 2015.Jan.. ( lets say total asset value for all entity = $100 in ECC and they just want to make sure in BPC this value is also $100)

Is there any BADI to pull this $100 value only in some Dummy member in BPC and run controls to check Dummy member = Total asset value ?

I hope my question was clear

Thanks
