AMDP in Release 7.51
Logical Database Schemas
Logical database schemas were introduced as symbolic names for physical
database schemas in
the SAP HANA database. Instead of physical database schemas, logical database schemas can be used by
frameworks (in particular AMDP methods) to access objects from different database schemas in Native SQL.

The ABAP runtime environment replaces these schemas on the database with the associated physical database schemas.
