DDIC External Views for SAP HANA Views in SAP HANA Repository (Obsolete)
ABAP_NOTE SAP HANA XSA replaces SAP HANA XSC. The access methods designed specifically for XSC objects are not suitable for XSA objects. After all XSC objects have been migrated to XSA, the access methods designed for XSC became mostly obsolete. DDIC external views represent one such access method and have become obsolete. More information can be found in SAP Notes 2465027 and 3116165.
AB_SQL can be used to access all database tables and views whose structures are defined as repository objects in the ABAP Dictionary. A SAP HANA view (attribute view, analytic view, or calculation view), on the other hand, is an entity of the SAP HANA database. This uses HANA-specific data types and different naming conventions than in the ABAP Dictionary also apply. This means that direct access to an SAP HANA view using AB_SQL is not possible.
In the ABAP Dictionary, views known as DDIC external views are used for direct access to an SAP HANA view in the SAP HANA Repository. A DDIC external view is a special view in the ABAP Dictionary that functions as a proxy for an SAP HANA view and which can be accessed using SAP HANA and AB_SQL .
DDIC external views are obsolete, see SAP Note 3116165.
