How To Fix RS_HCPR_MODEL102 - Cannot use navigation attribute &1 from PartProvider &2

RS_HCPR_MODEL102 - Overview

• Message type: E = Error

• Message class: RS_HCPR_MODEL - Messages related to the HANA Composite Provider Backend

• Message number: 102

• Message text: Cannot use navigation attribute &1 from PartProvider &2

What causes this issue?

The usage of a navigational attribute from a PartProvider is not
possible. The reason can be that the navigational attribute is not
switched on in the PartProvider or that the mapping of the navigational
attribute carrying characteristic in the Partprovider does not allow the
usage of the navigational attribute (e.g. a navigational attribute is
mapped to the navigational attribute carrying characteristic).
If this is a warning, the navigational attribute data has to be read
on-the-fly during execution of the query. If it is an error, on-the-fly
processing is not possible.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Switch on the navigational attribute in the corresponding PartProvider.
Only if it is switched on the navigational attribute can be read
directly from the PartProvider. Otherwise, the on-the-fly processing
takes place, not as good as the direct read from performance point of
view. If it is not possible to switch on the navigational attribute, a
different modeling is necessary. E.g. map navigational attributes to own
fields.
