Efficient options for SAP system copies
The steps to be taken before shutting down the target SAP system can be summarized as follows: Well before performing the upgrade, inform the target system users - especially project managers, developers, and testers - about the planned maintenance work via e-mail, SAP system messages, and/or a message at the system logon. Using the SAP transport system requires careful preparation so that software development projects can be completed as far as possible. Shortly before the start of the update, inform users again that maintenance work on the system is imminent and that they should log off from the target system. After logging users off and locking them out, download system-specific content from the target system database for customization (including security settings, Remote Function Call (RFC) targets, and operating modes).

With the definition of package groups, the parallel processing of packages can be configured beyond the definition of the order: All defined groups run in parallel to each other. For each group the parameters jobNum, taskArgs and loadArgs can be defined separately.

With "Shortcut for SAP Systems", tasks in the area of SAP system copying are simplified and can also be automated via the command line interface.

To ensure that SAP solutions are nevertheless used optimally, decision-makers are well advised to regularly subject IT landscapes and applications to intensive testing.
