How to load Multiple Account hierarchies into BPC from ECC

Hi,

We are working on BPC 10.0 NW consolidation model and have integrated the account hierarchy from ECC to  BPC 10.0.

But due to the reporting requirement, We are in need of 2nd hierarchy from ECC.

We wanted to retain the first hierarchy as Hier1 property in BPC and Hier2 as another property in BPC system and integrate both the Hierarchies from ECC.

I knew that multiple hierarchies can be maintained in BPC system, but wanted to understand how to load the second hierarchy into the system through the DMP with out hindering the 1st hierarchy.

Kindly help me with the same.

Regards,

Shilpa
