1. Reference to ABAP types

2. AMDP options

3. Logical HDI schemas

Other versions: 7.31 | 7.40 | 7.54

Modification 1

Reference to ABAP Types

When an AMDP method is implemented in an AMDP class with SQLScript, the following new AMDP macro

"$ABAP.type( [name =] abap_type )"

can be used to reference ABAP types. The ABAP runtime environment replaces these schemas on the database with the associated database types.

Modification 2

AMDP Options

The new addition AMDP OPTIONS for METHODS and CLASS-METHODS statements can be used to define attributes of AMDP methods in their declaration:

• The READ-ONLY option only allows reads in the implementation of the AMDP methods.
• The CDS SESSION CLIENT option sets the session variable of the database that can be addressed under the name$session.client in the CDS DDL of the ABAP CDS to a particular value when the method is called from ABAP. It avoids the warning from the syntax check and the exception CX_AMDP_CDS_CLIENT_MISMATCH when an AMDP method accesses the CDS database view of a CDS view whose client handling is determined by the annotation @ClientHandling.algorithm: #SESSION_VARIABLE.
  

Modification 3

Logical HDI Schemas

Alongside the existing logical database schemas, logical HDI containers can now be used as further logical schemas in the AMDP macro $ABAP.schema. The mapping of a physical database schema to a logical HDI container is made in the definition of an ABAP-managed HDI container, which itself links HDI objects to the Change and Transport System (CTS).
