ABAP_CDS in ABAP Release 7.60 ITOC
ABAP_MODIFICATION_NN CDS Access Control
ABAP CDS access control, introduced in ABAP_RELEASE 7.40, SP10, was expanded to include implicit evaluations of CDS roles defined in the ABAP CDS CDS DCL in AB_SQL . If a CDS entity is linked with a CDS role, an additional access condition is checked by default when the CDS entity is accessed using AB_SQL . Only that data is read for which the current user has an authorization or that matches a literal condition.
ABAP_MODIFICATION_NN Expressions and Functions
The following enhancements have been implemented:
The new SQL functions LENGTH, LTRIM, RTRIM, BINTOHEX, and HEXTOBIN are available for CDS views.
The special date functions DATS_DAYS_BETWEEN, DATS_ADD_DAYS, and DATS_ADD_MONTHS make it possible to calculate with values of the built-in dictionary type DATS in CDS views.
Data elements can now be specified as the target type in CAST expressions in a CDS view. This passes the semantic properties of the data element to the result. This also makes it possible to map more built-in types to itself than previously.
