Sap
Basis
SAP Basis is the glue
that holds together the SAP landscape. Different divisions of a business use
SAP to perform different jobs, such as shipping product, controlling, manufacturing, and tracking sales leads, but everything relies on the same core
system.
SAP Basisadministrators not only make sure all SAP components & applications can
communicate with each other, but do so with no end user or backend processing
performance degradation. Issues continuously crop up in any technical layer of
a SAP landscape and it’s up to SAP Basis support to keep the enterprise cloud,
database and application healthy. Basis administrators install updates, monitor
the system for errors and tweak SAP to be faster and more reliable.

SAP Basis Administrator: Responsibilities:
Architecting the Environment:
SAP Basis admins identify resources (such as
personnel, hardware and/or software) that are needed for successful
installations and upgrades, as well as to keep up with future use patterns
.
Implementing
Best Practices:
Business and Basis tasks intersect in complex ways
that can affect the way your organization runs. Basis staff
streamline these tasks to promote efficiency and ease of use.
User
administration:
Users are given roles in SAP corresponding to job
functions. An SAP Basis administrator fulfils user and role management
requests, such as provisioning roles to new hires, rescinding permissions when
workers leave, and spotting SOD conflicts between roles.
Managing
SAP Transports:
SAP transports (i.e. updates) need to be carefully
tested before they’re migrated to production. Admins must review transport
requests, configure and test transports, gather signatures and install
transports in the correct order.
Scheduling Background Jobs:
SAP background jobs are
what they sound like — routine processes that run in the background. An SAP
Basis administrator schedules and runs these jobs during times of low demand,
so that they don’t overburden system resources.
SAP Tuning:
The best SAP
administrators spend more time on Performance tuning than troubleshooting.
By analysing system performance, user demand and other factors, an SAP
administrator can ensure consistent performance and avoid the need for heroics.
Disaster Recovery/High Availability:
An SAP administrator is
responsible for backing up and restoring the environment, and testing the
backup systems. These SAP Basis administration tasks are often outsourced to
a cloud disaster recovery partner, who can generally improve reliability
and lower costs.

defined as an arrangement of SAP servers. Ideally, in a Sap environment, a
three-system landscape exists. A system landscape consists of Development
Server (Dev.), Production Server (PROD), and Quality Assurance server (QAS).
