SAP S/4HANA Cloud Public Edition

Custom CDS views

Custom CDS Views created in the Custom CDS Views app are key user extensibility objects and cannot be used by developer extensibility objects. For more information, Refer to Key User Extensibility.

To deploy a RAP based application in SAP S/4HANA Cloud Public Edition using Eclipse, need to create a "Service Binding" within the context of developer extensibility.

In the context of Developer Extensibility, only custom UIs based on custom business services build in ABAP Environment can be deployed to the SAP S/4HANA Cloud development tenant.

Standard CDS views

If a CDS view is released for cloud development (developer extensibility), it's available for reuse in the SAP S/4HANA Cloud ABAP Environment.

You can find all CDS views released for this use case in the repository tree Released Objects > USE_IN_CLOUD_DEVELOPMENT within the ABAP Environment.

Please check whether "I_XYZ" is released for cloud development in ABAP Environment by simply going to "ABAP Environment > Navigate > Open ABAP Development Object" where it is possible to add a search string like: api:USE_IN_CLOUD_DEVELOPMENT I_XYZ

You can also check the release state in the View Browser app ("Cloud Dev. Rel. State" column).
