BPs in Customer Hierarchy CRM downloaded from ERP

Hello,

I downloaded the Customer Hierarchy type A from ERP to type 01 CRM successfully as mentioned in the SAP help and all other posts I find here regarding this topic.

Now I have the hierarchy named R3-CRM-01 in CRM and want to work with this. But when I look at it, it only is a tree of nodes with the customer numbers and salesorgs in the name but absolutely NO Account is assigned to them.

Is this the standard behaviour?

How do I work with that, because I have to find out where my current customer is in the hierarchy?

Function Module like BUHI_GET_PATH will only work if the BP is assigned to a node in the tree,

Can someone clarify what to do here?

Thank you very much!

Michael
