Hierarchy structure difference between bw and bpc

Hi Experts,

We are loading masterdata from bw to bpc for Acoount dimension.we have an extra node in BPC for PBT member but not exists in BW. For this everytime we have to change the account structure manually after completion of bw loading. Is there any work around to fix this?

Thanks for your help.
