ABAP_SYNTAX ... PROVIDER CONTRACTS INA $| SQL ...
What does it do? A provider contract can optionally be specified in a CDS service definition. It defines the scenario for which the service definition in question is intended. The effect is that stricter syntax checks are applied. Currently, the following provider contracts are available:
INA Switches on syntax checks that are needed if the service definition is published with the Information Access (InA) protocol. When this provider contract is specified, the following additional rules apply:
The CDS entities exposed must be analytical queries. Two kinds of analytical query are acceptable:
Analytical queries with the annotation @Analytics.query set to true
CDS projection views with the provider contract analytical_query .
If the exposed CDS entity is an analytical query with the annotation @Analytics.query: true , exactly one entity must be exposed. Otherwise, a syntax check error occurs.
If the exposed CDS entity is a CDS projection view with the provider contract analytical_query, then multiple entities can be exposed.
SQL Switches on syntax checks that are needed if the service definition is published with the service binding type SQL. The same checks are performed as for service bindings of type SQL. The checks are documented on SAP Help Portal in the Developer Extensibility Guide, topic Constraints. Exactly one provider contract can be specified in a CDS service definition. Changing the value defined after PROVIDER CONTRACTS is possible, even after activation and transport of the respective service definition, as long as the corresponding service binding is not affected.
ABAP_USE_CASE A provider contract is a prerequisite for releasing a CDS service definition under the C0 contract, extend. It enforces strict rules that match the rules of a type of service binding. This ensures stability of business services and prevents service definition extensions from causing errors in the associated service bindings.
