3789380 - OpenAPI: SAP Ariba API does not return child-to-parent group relationships (only parent-to-child)

I need to extract the child-to-parent relationship of user groups in Ariba. The existing Open APIs do not provide a direct method to retrieve child-to-parent group relationships; it only exposes the parent-to-child hierarchy.
