Working with navigational attributes in Composite Providers

While working with Composite Providers (HCPR) a navigation attributes of InfoObjects that are present in objects contained in the HCPR are not shown by default. Below picture illustrates how it looks like when the navigation attributes are not shown.

In BW Modelling Tools  of SAP HANA Studio there is an option how to enable it. In the HCPR maintenance screen under a right click there is an option called “Show Unassigned Navigation Attributes”.

Once the above option is activated then the navigation attributes are present and can be freely assigned. Here’s how does it look like when the navigation attributes are available.
