Loading hierarchy from BPC Dimension to BW infoobject in the backend

Hi,

We have a custom hierarchy being used in SAP BPC and the requirement is use the same hierarchy in SAP BW. Its not getting loaded via ECC.

Is there a way we can load this custom hierarchy from SAP BPC dimension to a BW characteristic. Pls note that we cant use a new object as reference of BPC object as the requirement is to have this for a existing infoobject.

Thanks

SK
