3590634 - Inability to Use CDS View Entity as Association Targets in Custom Business Objects - SAP S/4HANA Cloud Public Edition

• A CDS View Entity is created by ADT and released as C1 contract(Use in Key User Apps). 
• However, the CDS View Entity is not usable in a Custom Business Object (CBO) when creating a field of which type is Association to Business Object.

• ABAP Development Tools
• SAP S/4HANA Cloud Public Edition

Custom Business Objects only permits the association of Business Objects, not simple CDS Views. This is the intended behavior of the system.

At present the registration of other business objects as association targets is governed by a process that is neither driven by annotations nor intended for use outside of SAPs own development.
