Add Annotations to OData Service based on exposed CDS View

[former_member204167]

Hi Experts,

we have exposed a CDS View via OData Annotation (@OData.publish: true). I know that a lot of annotations for such an OData service can be achieved by using various CDS annotations but how can I add some vocubulary based annotations to such an Odata Service that are not available for CDS yet e.g. a term like "com.sap.vocabularies.Common.v1.ValueList"?

Is there a way to create an OData extension project for these special kind of services? Though the regular extension (with OData Extension Projects in the service builder) technically works I encountered several issues that I couldn't fix.

Regards

Tobias

Dear Tobias,

you could create an annotation model project in SEGW. In this project you can reference your service and add annotations like in the vocabulary-based annotations service. The annotation model will be also suggested in Web IDE, when you create a new application for your service.

Hi,

thanks for your reply. I did this once for a "Service with SAP Annotations" to add some vocabulary based annotations without coding and it worked fine. In this particular case here my original service already uses vocabulary based annotations. Is it possible though to use a referenced annotation model using the same vocabularies. Since my original service is a generated one I cannot manipulate the annotations there.

I can reference a CDS-published service in an annotation model project in SEGW.

You can add a local annotation to your package by SAP Web IDE.

It provides a Annotation Editor.
