What is a Client in SAP?
In SAP, a client is the highest organizational unit
in the system. It serves as a self-contained business entity with its own
master data, configuration, and user settings. All SAP systems can host
multiple clients for development, testing, training, or production purposes.
Why SAP Client Copy is Important
SAP client copy allows administrators to replicate client
data across systems or within the same system. Common use cases include:
- Creating
test environments from production data
- Refreshing
training or sandbox clients
- Preparing
QA systems with real data
- Archiving
or migrating historical configurations
Types of SAP Client Copy Methods
1. Local Client Copy (SCCL)
- Performed
within the same SAP system
- Ideal
for copying from one client to another within the same system
- Uses
transaction code SCCL
- Requires
source client to be accessible
- Options
include profile types like SAP_ALL, SAP_CUST, or SAP_USER
2. Remote Client Copy (SCC9)
- Performed
between two different SAP systems
- Source
and target systems must be connected via RFC
- Uses SCC9
for execution and SCC8 in the source for export authorization
3. Client Export/Import
- Involves
exporting the client from the source system and importing it into the
target system
- Export
via SCC8
- Import
via STMS after transporting files
- Useful
when RFC is not available between systems
Client Copy Profiles and Their Use
|
Profile |
Purpose |
|
SAP_ALL |
Complete copy including user and application data |
|
SAP_CUST |
Customizing data only |
|
SAP_USER |
User master data and authorizations |
|
SAP_UCSV |
User data, customizing, and selected tables |
Step-by-Step: Local Client Copy Using SCCL
Pre-requisites:
- Target
client should already exist (created via transaction SCC4)
- Source
client should have necessary data
- Background
jobs should be configured for long-running operations
Steps:
- Log
into the target client
- Go to
transaction SCCL
- Select
the source client
- Choose
the appropriate copy profile (e.g., SAP_ALL)
- Start
the copy as a background job
- Monitor
progress using SM37 or SCC3
Client Export and Import Process
Client Export (SCC8):
- Run
transaction SCC8 in source client
- Select
appropriate profile
- Choose
the target system transport route
- Execute
export, which creates transport requests
Client Import:
- Use STMS
in target system
- Import
the transport requests
- Use SCC7
to perform post-import client copy steps
- Monitor
with SCC3
Client Management Best Practices
- Always
perform a client copy in background mode
- Schedule
during low system load times
- Take a
full database backup before performing export/import
- Lock
users during copy to avoid inconsistencies
- Monitor
logs in SCC3 for any errors or warnings
- Use client-specific
authorizations and lock sensitive clients

Client Copy (SCCL)
- Remote
Client Copy (SCC9)

copies data from a source client to a target client.
5. What is SCC9 used for?
Answer:
SCC9 is used for remote client copy where the source and target clients
