• Message text: Navigation attribute &2 is not a selection attribute

What causes this issue?

Navigation attributes are automatically defined as selection attributes

can be linked to a local selection attribute. In this case, you can
define the navigation attribute as a display attribute if you want to
have such a link.
However, navigation attribute &V2& of characteristic &V1& is neither
selected as a selection attribute, nor linked to a local selection
attribute.

System Response

The settings for attribute &V2& of characteristic &V1& are inconsistent
and cannot be saved.

How to fix this error?

If you want to link attribute &V2& of characteristic &V1& with a local
attribute, enter the link in the data basis customizing settings. Make
sure that the local attribute is defined as a selection attribute.
Otherwise, set attribute &V2& of characteristic &V1& as a selection
attribute.
