- Projection Views

A DDIC projection view is a special view for hiding fields from a single basis table. An SQL view is not created on the database. No selection conditions can be specified for a DDIC projection view.

The structure type defined using the view fields of the projection view can be referenced in ABAP programs using TYPE. A projection view can be accessed using but not using CDS views, Native SQL, or AMDP. The database interface transforms an statement that accesses a projection view to a platform-dependent SQL statement that provides the correct result.

The Access setting in the maintenance status of a projection view can have the following values:

• Read only

The projection view can only be used to read data with .

• Read, change, delete, and insert

The projection view can only be used to change data with .

When lines are inserted using projection views, all table fields not in the view are given the type-specific initial values of the field. This is done regardless of whether the field is defined as NOT NULL on the database.

Notes

• As in a DDIC database table, the client dependency of a projection view is determined by an initial column with the built-in dictionary type CLNT.

• Like a DDIC database table, the maintenance status of a projection view has a Display and Maintain setting alongside the Access setting. The setting must match the Access setting.

• The basis table of a projection view can be a transparent table and a global temporary table.

Example

The projection view DEMO_SPFLI contains fields of the tables SPFLI. The view can be accessed as follows using :
