Effect
A path expression in the CDS DDL is a sequence of CDS associations separated by periods (.) whose names are specified using assoc1, assoc2, and so on.
In analytical projection views, path expressions are only supported in the following scenarios:
- Language dependencies implemented using the keyword LOCALIZED.
- Temporal dependencies implemented in the following format:
- [1:date_from <= $parameter.key_date && date_to >= $parameter.key_date]
- key_date can be a parameter, a session variable, or a literal. It must be typed with DATS or DATN. It must be annotated with @Semantics.businessDate.
Note
Fields included via path expressions can be texts, display attributes, or texts belonging to display attributes. In an analytical cube view, such fields might be text or foreign key associations. In a CDS dimension view, such fields can be text associations.
Example
The following CDS analytical projection view DEMO_ANALYTICAL_QUERY defines an analytical query. It is based on the cube view DEMO_CDS_CUBE_VIEW. It contains a path expression to a localized text element CurrencyDescription.
