How to load parent member (store data type) with dynamic cal children account?

Summary:

I did integration from FCCS to PBCS but always failed to load parent member (store data type) with dynamic cal children account.

FYI

In FCCS the parent account data type is dynamic calc while its childrens is never share type.

But, in PBCS the parent account data type is store while its children is dynamic and store data. I can't change the data type because there's script in the store account.
