Describe the Bug

Hello,
In patch requests build with the fluent API, updates of deep (association like) attributes are ignored. From Update field of a property with complex type in OData Client V2 and Support deep update with complex type via odata clients one understands that this is support to work. We are using cloud SDK 5.26.
Best regards
Axel.

Steps to Reproduce

1. Clone the repository https://github.tools.sap/CALMBuild/ptm-lib-srv.git.
2. Use the attached settings file in ~/home/.m2.
3. Run mvn clean install
4. Run the cucumber test scenario I can use the API to add and remove assignments to developments using deep update in file src/test/resources/com.sap.calm.imp.lib.app.v1/ApplicationUpdate.feature.
5. Set a break-point in method iUseTheAPIToPatchTheApplicationWithTheUUIDWithTheFollowingData of class ApplicationUpdate to check that object application contains data for toLibraryAssignments.
6. Set a breakpoint in the CDS event handler beforeUpdateApplications in class APIApplicationsHandler and check there that the complex property toLibraryAssignments was stripped off.

Please note that complex creation seems to work and that CAP CDS is supports deep update.
