build an OData navigation property with parameters that can be $expand-ed

Hello Colleagues

We try to build an association of two entities which both have parameters. They are linked with a navigation property.

Now, we try to $expand the dependent entity within the referencing entity. But the HANA Developer Guide states that the $expand is not supported for this type of navigation property (see as well SAP HANA Developer Guide for SAP HANA Studio - SAP Library).

Is it still true that expansion of such association is not supported?

Is there a workaround?

Is it planned to support this some-when?

Thanks and best regards

Dani
