Funds management-Funds center creation

Hi Gurus

I am in the process implementing FM.

I am creating funds centers but I'm encountering some challenges;

1. I started off by creating a Hierarchy but I'm stuck at Hierarchy Variant. What do I do here?

I also want to know how to use this variant and how to obtain it.

2. I would like to map CCtr/PCtr/Funds Center. I do have the CCtr and PCtr structures in CO. I would like to replicate the CCtr structure in FM Can I use it in FM and if so how? I think this summarises my problem

Kind regards
