SAP System Landscape
Before going deeper into SAP Basis, it is important to understand common SAP terminology like Client, Instance & SID.
SAP Client – It represents a self-contained unit in SAP environment with separate master & transaction data. For example, a multinational organization can have separate clients for each subsidiary like US Client, IN Client, AU Client etc.
SAP Instance – It refers to the group of processes that are started & stopped together. SAP systems will always have at least one instance running known as Central Services Instance.
SAP SID – It stands for "System ID" and is a unique identifier for each SAP instance. All instances need to be assigned a 3 character SID like ECC, ERP, QAS, PRD etc. that differentiates them.
An organization can have a landscape with multiple SAP systems distributed globally across different data centers. There can also be complex system landscapes with multiple clients and instances for testing, development, quality assurance, production etc.
SAP Basis administrators are responsible for setting up this system landscape and ensuring seamless communication between these systems.
SAP Architecture Overview
SAP is built on 3-Tier Architecture comprising of:
1. Database Tier – This includes the backend databases like Oracle, DB2, HANA etc that store business data, configurations and master data.
2. Application Tier – This tier contains business logic and runs SAP applications. It includes various SAP modules and system landscape components.
3. Presentation Tier – It contains frontend client software and provides user interface for accessing SAP systems. SAP GUI is an example of presentation tier component.
The application tier communicates with database tier using SQL connections whereas presentation tier communicates with application tier using proprietary SAP protocols like RFC, HTTP etc.
Let‘s now get into some key SAP Basis activities and components in detail:
Client Administration
Client administration involves managing organizational structure in SAP by creating separate units called "clients" – something we have already discussed.
Each client contains separate master & transaction data. Configurations like SPRO settings, roles, RFC destinations etc. are also client specific.
Some common SAP tcodes useful for client administration are:
- SCC4 – Create New Client
- SCC5 – Client Copy
- SCC6 – Delete Client
- SCC7 – Client Transport
- SCC8/SCC9 – Additional Client Administration
Steps to create a new Client
- Enter tcode SCC4 in SAP command field
- Click on ‘‘New Entries‘‘ button
- Specify 3 character client code
- Enter Description details
- Select Data transfer method – local/remote
- Click on Save icon
This adds a new client. Once added, other client administration activities can be done like assigning users, copying data from an existing client etc.
Transport Management System
The Transport Management System (TMS) in SAP manages movement of data, configurations or custom code between systems across the landscape.
It ensures integrity & consistency by allowing orderly deployment of changes through proper change control procedures.
TMS has 3 key components:
1. Transport Domain – Group of SAP systems tied together by TMS
2. Transport Route – Path for movement of changes between SAP systems
3. Transport Request – Vehicle for transferring changes from one system to another
To setup TMS, systems need to be configured as Development, Quality & Production by creating Transport routes & layers.
Post this configuration, any custom changes need to be imported & exported through transport requests for migration across systems.
Some key tcodes for Transport Management are:
- SE03 – Transport Organizer
- SE09 – Create Transport Request
- SE10 – Import/Export Transport Request
- STMS – Transport Domain Management
So in summary, TMS ensures controlled change management across connected SAP landscapes.
Job Scheduling vs Process Chains vs Batch Jobs
Basis administrators have 3 options for running automated tasks in background:
1. Batch Jobs – Legacy option for basic background processing of data using ABAP programs or external commands.
2. Job Scheduler – Improved batch job functionality allowing chaining of jobs, interdependencies, calendars etc.
3. Process Chains – High degree of automation for orchestrating various jobs and steps involving complex business processes.
While basic background jobs and scheduler meet simple needs, process chains allow modeling entire business processes having sequencing, conditions, dependencies etc.
But key advantage of all 3 options is task automation by avoiding manual intervention.
Print Spool Administration
Print administration deals with configuration of print infrastructure by setting up:
1. Printers – Output devices like local/network printer
2. Forms – Document templates having layout for print output
3. Spools – Storage location that holds print data
The print spooler helps optimize high volume printing by sorting, distributing and monitoring print jobs across the network.
Some key capabilities offered by print spooler are – load balancing, error recovery, prioritization, system independent output etc.
Relevant tcodes for print administration are – SP01, SP02, SPAD, SP12, SP13, SPOOL and PF06. So in summary, an efficient spool ensures optimal printing.
User Administration
Another important function of SAP Basis is User Administration which involves tasks like:
- Creating users
- Assigning authorizations & roles
- Locking/unlocking users
- Password management
- Setting login parameters
- User master & Profile management
Primary tcodes for user administration are:
- SU01 – Create/Maintain Users
- SU10 – Unlock Users
- SU03 – Maintain Authorizations
- SU24 – Mass User Maintenance.
There are also many additional tcodes catering to specific user admin needs.
Effective user access control is critical for security and preventing frauds.
Background Job Management
Certain tasks in SAP like report generation, data load jobs, index rebuilds etc can be run in background freeing up resources for online processes.
These jobs are managed by the job scheduler and get added to job queues for processing based on defined schedules and priorities.
Background job lifecycle involves steps like:
- Creating a job
- Submitting it for processing
- Monitoring status
- Viewing logs
- Rescheduling
- Deleting jobs
Major tcodes for background job management are:
- SM36 – Create & Schedule Jobs
- SM37 – Monitor Job Status
- SM21 – Administer Job System
So in essence, SAP job scheduler allows scheduling of jobs for automated execution.
Intelligent Basis Troubleshooting
SAP systems need to be proactively monitored for identifying issues before they cause disruption to business operations.
While traditional manual troubleshooting is complex and time consuming, AI can drive intelligent automation.
Machine learning algorithms can automatically:
- Analyze historical tickets
- Identify troubleshooting steps followed for resolving similar past issues
- Apply pattern matching to new incidents
- Recommend most relevant troubleshooting flow
This allows basis engineers to quickly diagnose and fix problems based on lessons learnt.
According to internal SAP study, AI-based troubleshooting reduced resolution time by 20%.
SAP Monitoring & Troubleshooting
Important parameters like CPU usage, database connections, locks, logs, dumps, services etc. need monitoring for identifying technical problems or bottlenecks.
Some standard SAP transactions useful for monitoring are:
- ST04 – Application Server Performance Statistics
- ST05 – Database Connection Statistics
- ST06 – Page Buffer Statistics
- ST07 – Database Lock Statistics
- SM50/SM51/SM66 – Manage & Monitor SAP Services
In addition to problem identification, technical troubleshooting is also a critical Basis activity for diagnosing and resolving system issues.
Things to analyze during troubleshooting – Dumps, Trace Files, Logs, Kernel Messages etc.
So robust monitoring combined with rapid troubleshooting enables high SAP system availability.
Backup & Recovery
Taking regular backups is essential for recovering SAP systems in case of disasters. Backup/Recovery in SAP can be performed at:
1. Database Layer – Using native database tools like Oracle RMAN, HANA Backup etc.
2. File System Layer – Using third party backup software like Commvault, Netbackup etc.
Most organizations implement a daily incremental + weekly full backup schedule.
Some Standard transactions used for backup monitoring & management are:
- DBACOCKPIT – Database Administration Cockpit
- BACKINT – Backup Interface Management
- BRRESTORE – Backup Restore Trans Manager
Additional Concepts with SAP HANA
- Storage Snapshots
- Delta merge backups
- Backup catalog
- Point in Time Recovery
So in summary, a sound backup strategy is critical for minimizing disruption due to data loss.
System Copy Scenarios
Basis administrators need to frequently create copies of existing systems for variety of business scenarios like:
1. Testing latest support packages
2. User training
3. Mass testing of master data
4. Sandbox for new configuration testing
To speed up copying systems, SAP provides tools like SWPM, Cloning and System Replication.
As per survey by The Hackett Group, these SAP tools reduce duplication efforts by 60%.
So leveraging system copy capabilities leads to faster implementation of projects requiring fresh systems.
Upgrades & Maintenance
Regular upgrades & maintenance activities ensure systems are updated with latest kernels, support package stacks and security fixes.
Some common upgrade scenarios are:
- Unicode Conversion
