Replicating Article Hierarchies from SAP ERP to SAP CRM

Article Hierarchy is configured in SAP Retail, therefore its is visible via Transaction WMATGRP03.

We wish to download the Article Hierarchies from SAP Retail (SAP ERP) to SAP CRM.

The issue is that we did not find standard mechanism for downloading the Article Hierarchy from SAP Retail (SAP ERP) to SAP CRM.

Is there a way to replicate the Article Hierarchies into SAP CRM? I'm very interested to hear what options are available.

We only found this information: http://help.sap.com/erp2005_ehp_07/helpdata/en/a7/dec353b677b44ce10000000a174cb4/content.htm?frameset=/en/65/dec353b677b44ce10000000a174cb4/frameset.htm&current_toc=/en/d3/dec353b677b44ce10000000a174cb4/plain.htm&node_id=21
