What does it do?
Defines a data source of a ABAP_CDS_V1_VIEW . A data source can be a DDIC database table defined in ABAP Dictionary
BEGIN_SECTION VERSION 5 OUT , a DDIC database view, an DDIC external view,
END_SECTION VERSION 5 OUT a CDS view entity, a CDS table function, a CDS hierarchy, or a ABAP_CDS_V1_VIEW .
The data source is specified either directly using its name entity or using a path expression path_expr in which CDS associations are evaluated. Non-SQL CDS entities are not possible as association target of the path expression.
If the data source is a CDS entity with a list of input parameters, actual parameters must be passed to these using parameters.
An alternative name alias for a directly specified data source can be defined after AS. It is also possible to define an alias name without the keyword AS (see example below). If a path expression is used, an alternative name must be defined. The name must comply with the naming rules for names.
The syntax JOIN can be used to combine multiple data sources as joins.

DDLS DEMO_BUSINESS_PARTNER_2
ABAP_EXAMPLE_END
