we are in the design phase of an unmanaged transactional application development with the SAP - ABAP RESTful Programming Model.
Concretely we are working on the Business Object Structure.
It is possible to define the Business Object Structure as CDS views in a parent child relationship with the keywords root, composition of and association to parent.
Additional it is possible to define usual CDS associations (association to).
Is it intended to use the keywords composition and association to parent and association to mixed in one Business Object Structure?
If yes, how should we decide when using composition / association to parent or association to in order to get a stable Business Object Structure?
Thanks in advance for the answers.
