Copying needs to be done skillfully
Ways of SAP system copy: export / import
Table splitting reduces the risk of losing a lot of time during export in case of an error. When restarting, the complete table does not have to be exported again, but only a subset. Simultaneous processing of a table by several R3load processes can reduce the total runtime for this table.
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.
SAP Landscape Copies
Over 30 productive systems at more than 9 customers successfully copied using IMIG. For the Unicode conversion of a 4.5 TB system (2.7 TB data) a downtime of 16 hours was achieved (including the follow-up work such as reconfiguration, updating DB statistics, generating reports, creating backups, testing the system).
The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
You should also create a delta list for all transports that have not yet reached the production system. Software contained in open transports is lost during the upgrade, which may seem useful for cleaning up the system, but can have dire consequences for development projects. That's why you should take a close look at delta transport lists before proceeding with the upgrade. UC4 Automated System Copy allows you to automate the above steps. If necessary, you can add additional steps without losing testing capabilities.

Nevertheless, the special system architecture and the peculiarities of the DB2 database integrated in the operating system, as well as the specific applications, also pose challenges for system tool developers.
