When an SAP HANA Cloud, data lake instance is provisioned, the system automatically creates a dedicated administrative user named HDLADMIN. This user is granted the necessary system privileges (e.g., HDLADMIN role) to perform all administrative tasks within that specific data lake instance. This includes managing other users, roles, and monitoring the data lake environment. The HDLADMIN user is distinct from the administrative user of the associated SAP HANA database (which is DBADMIN).

B. SAPSA: This is the default system administrator user for the on-premise SAP IQ database, which is the technological predecessor to the SAP HANA Cloud, data lake.

C. DBA: This is a generic term for "Database Administrator" and is not the specific name of the default user created for the SAP HANA Cloud, data lake.

D. DBADMIN: This is the initial administrative user created for the SAP HANA Cloud, SAP HANA database instance, not for the data lake component that is added to it.

2. SAP HANA Cloud

SAP HANA Database Administration Guide: This guide clarifies the role of the DBADMIN user. In the section "Initial Database User

" it specifies

"The user DBADMIN is the initial database user that is created when an SAP HANA database instance is created... The DBADMIN user is a database administrator of the SAP HANA database." This confirms DBADMIN is for the HANA database

not the data lake.
