ABAP_RAP - RAP BO with DCL Access Control This example demonstrates how read access control is implemented and evaluated for a RAP BO for active data and for draft data using the CDS data control language CDS DCL. Data model The CDS data model consists of the root view entity DEMO_RAP_MANAGED_DRAFT_QUERY. DDLS DEMO_RAP_MANAGED_DRAFT_QUERY This CDS root view entity has the CDS DCL access condition DEMO_RAP_DRAFT_QUERY attached to it, which restricts read access to the active data. DCLS DEMO_RAP_DRAFT_QUERY Draft Query View The following CDS view entity DEMO_RAP_DRAFT_QUERY_VIEW defines a draft query view. It selects all fields from a RAP draft table. It has a CDS DCL source attached to it, which defines read access restrictions for the draft data. DDLS DEMO_RAP_DRAFT_QUERY_VIEW This CDS view entity has the CDS DCL access condition DEMO_RAP_DCL_DRAFT attached to it, which restricts read access to the draft data. DCLS DEMO_RAP_DCL_DRAFT Behavior definition The RAP behavior definition DEMO_RAP_MANAGED_DRAFT_QUERY is managed and draft-enabled. It specifies the CDS view entity DEMO_RAP_DRAFT_QUERY_VIEW as draft query view. ABAP_NOTE This example is intentionally kept short and simple and serves demonstration purposes only. The RAP handler methods are not implemented in the ABAP behavior pool here. BDEF DEMO_RAP_MANAGED_DRAFT_QUERY
ABAP_DESCRIPTION Access with ABAP using EML and AB_SQL The above source code uses EML and AB_SQL to access the RAP business object from an ABAP class:
It creates four active entity instances using the EML statement MODIFY ENTITIES CREATE.
It reads these active instances, first with the EML statement READ ENTITIES, and afterwards with AB_SQL SELECT. In the EML read, the DCL access condition is applied and the result set is filtered according to the access condition. Some data sets are filtered out. By contrast, the AB_SQL SELECT displays all instances that were saved on the database.
