Set up Corporate Customer Tree

Hi, We are upgrading to PeopleSoft 9.2 version. I need to create corporate customer tree in FSCM. When I try to add a new corporate customer tree under the navigation path Customers > Customer Information >> Corporate Customer Tree, the tree node does not have any value and it is required field of the record CORP_NODE_AR which is the base record for the corporate customer tree. Please let me know how can I add a new corporate customer tree.
