Error with table with a key in navigation property

[VanessaSap]

Hello,

When I try to implement Change Tracking on a table where the key is a navigation property, I get the following error:

"Error: CDS compilation failed (@sap/cds-compiler v5.4.0)
srv/admin-service.cds:408:45: Error: Unexpected usage of structured type “to_Rule” (in entity:“RulesDerivation”/column:“changes”/on)"

entity RuleDerivation : managed {
key to_Rule : Association to design.Rule
...
}

Could you help me understand if there’s a way to work around this problem?
