Copying needs to be done skillfully
SAP system startup and shutdown, including virtual hosts
Table splitting requires 2 tools: R3ta, which determines the WHERE conditions used to access subsets of a table. TableSplitter, which splits the WHERE-conditions determined by R3ta into packages with one or more subsets.
Basically, a distinction is made between the initial setup and refresh of a non-productive SAP system. In the past, the cost of a refresh, i.e., updating the environment with new data, often corresponded to the cost of the initial setup. This also restricted the availability of the productive system, which is hardly tolerable for companies that operate internationally and in different time zones.
SAP system deployment scenarios
To build a target system that can be used for testing, development and training purposes, there are two different approaches: Users can reinstall an SAP system and import all transports and support packages that have also made it into the production system to date. However, when their number reaches the hundreds and thousands, the effort becomes disproportionately high. In addition, the data still has to be imported from the production system, for example via a client copy.
After restarting the target system The SAP target instance has been started with a database that has been updated with content copied from the production database using fast and scalable disk array replication. The status of the target system now allows it to run without severe internal errors and disruption to the SAP landscape. However, the system does not have the same identity in the SAP landscape as it had before the update. That's why post-processing is required. UC4 Automated System Copy can handle most of the post-processing by restoring specific database content customizations (such as security settings, RFC targets, and operating modes) that were downloaded before the upgrade. Another goal in post-processing is to change the production system's logical system names to those used by the target system. Since these names usually need to be passed to numerous tables in a given system that have not yet been customized, SAP has the BDLS transaction that can be used to safely analyze and change logical system names. UC4 Automated System Copy can automate and accelerate this transaction by analyzing the underlying processes and executing them in parallel. It can also automate tasks such as reorganizing spools and instructing transport managers to process the delta transport list.

For each group the parameters jobNum, taskArgs and loadArgs can be defined separately.
The term "system copy" describes the process of creating a copy of an SAP system on a new server.
