ABENCDS_PV_NO_CONTRACT - CDS PV NO CONTRACT

- CDS Projection View, No Contract

It is possible, but not recommended, to define a CDS projection view without a provider contract. The default provider contract, if no provider contract is set explicitly, is TRANSACTIONAL_QUERY. The same features are available as for transactional queries and a projection view without provider contract can be used in the same scenarios. However, there are some minor differences in the syntax checks applied:

• In a transactional projection view with provider contract TRANSACTIONAL_QUERY, path fields path_expr.element can be used in an association ON condition via $projection. In a projection view without provider contract, this is not allowed.

Example:
Field in the projection list:
_assoc.fieldName
This path field can be used in an association ON condition in a transactional query, but not in a projection view without provider contract:
... on $projection.fieldName = 'A' ...
