Abstract: The client copy tool has been renovated and will include multiple updates, starting with SAP NetWeaver Application Server for ABAP 7.54. Join us as our speakers dive into these renovations, including the SAP HANA-optimized local and remote client copy, client deletion, client export and import tool, client comparison tool, and client size estimation tool. (source: SAP)
Please note that this is about ABAP tools, not Java
Not official roll out
If share information regard outlook, usual disclaimer applies
Why revisit? Existing client copy tool existed for 20 years
Why revisit? Driver was S/4HANA Cloud and SAP HEC had similar requirements
Cloud has no system downtime, no server restart, reduce runtime of copy
Log is now written to a table, not a file
High coverage of test automation
Compare business configuration in 2 clients
Right shows KPI’s and constraints
Logon to target client
New architecture – automate, box to the right lower column
Introduce tasks in task manager tool; strategic UI for all related processes, from client 0 copy is started
Transfer from one to another
Remote scenario – data pulled from another system
ABAP stack – pure movement of data process – could be done on a database
Application exits, domain executed code
Application excludes certain tables
Timeline: started in 2017
Decided to reimpliment tool
May 2019 in S/4HANA Multi tenant environment – new automation, productive use in cloud
In 1909 in September
Intend new tool as standard, plan to deprecate old tool
New client copy tool comes with task list, and new log, an ALV-based table instead of log files
Back end transaction for tool and log
Completely reinvented
Improved performance; new tool is 10 times faster than old
Remote copy is 5 times faster
Usability is improved
Do not need SAP* user
New stability – handle large database, and can split tables so it can run parallel
Old tool: logon to target client
New tool – run in tool in client 000
Advantage is SAP* user is not needed
Data remains in database layer
Data does not reach ABAP Layer
New client import and export ool
New transactions, task list
Use SCC8N
Use SCC7N
Advantage is the offline client copy
New client comparison
Two modes – checksum — fast compare, less details
Detailed comparison for troubleshooting
Calculation based on size of table in database divided by rows in client
New log, ALV-based
New transaction – SCC3

Question & Answer:
Does this tool work with SAP SRM and SLM?
It is available with S/4HANA 1909 onwards only (and other SAP Products on same BASIS Stack)
What is the transaction to check this client copy log?
SCC3 (same as before, it checks if copy was made with new tool, then new log is shown)
What will happen when we don’t select option “Lock source client” while doing local client copy. Can we anticipate wait time?
source system has 100K database tables – worst case could lead to inconsistent tables
How does the Client export works for Huge databases for eg 5 tb to be used for system refresh Prod to QA.How efficient is it now compared to before?
client export – no change for large db tables; client export works on transport request
