Message no. SADL_GW_DT_CDS025

Diagnosis
The association that is annotated with @ObjectModel.association.type: #TO_COMPOSITION_ROOT is defined multiple times, either in the local CDS view or through an inheritance from an underlying CDS view.

Define the association annotated with @ObjectModel.association.type: #TO_COMPOSITION_ROOT only once.

1. Open CDS View

This issue was caused by a change in the DDIC in the inheritance of association annotations.

Development is researching this complex issue and will provide a solution when available.
