Product replication from ECC to Marketing cloud

Hello Experts,

We are replicating the products from ECC to Marketing cloud. We also need to replicate the product hierarchy as well in the following fields highlighted.

Can you please confirm how to replicate the product hierarchy from ECC to Marketing cloud.

1. Do we need to use the seperate iflow which is specifically used for the product Hierarchy replication.

2. Can this be done with the standard iflow as we are getting the code and we have loaded the code list mapping in marketing cloud system.

3. Please let me know the specific iflow to be used and some guidance as I am not able to replicate the fields.

your help will be really appreciated.
