Tools for SAP test systems
Synonym(s): SAP System Refresh, SAP System Copy, SAP Client Copy, SAP Client Copy, Landscape Copy, Landscape Copy
If the data stocks become obsolete, they can be updated by another system copy. From a technical point of view, such a refresh corresponds to the initial setup, including the associated costs as well as the load on the productive systems and manual rework. In addition, a refresh also interrupts all processes on the target system. If it is a development system, all newer development objects must be saved and transported back in after the copy. The version history is lost in the process.
SAP offers its own solution for this: With the Test Data Migration Server (TDMS), individual tables can be selected and written indirectly, via a third SAP system, from the source to the target system via Remote Function Call (RFC). However, the selection of business objects is not possible in the standard system. The tables to be copied can only be determined on the basis of the date. The content restriction applies from a certain point in time. At least the SAP tool can be used to reduce the runtime of an extraction of test data compared to the system copy or client copy.
The guideline that integrated job logic is preferable to customizing has also proven its worth. The key point here is that each step of a copy job knows the overall context, including the steps that preceded and follow it.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
A system copy can be created either with SAP transactions (R3trans, from R4.6C SAPinst) or at file and database level. Costs and effort increase with the size of the system and the requirements for availability and data protection. In addition, administrative rework is often necessary, starting with the system name and extending to printers and interfaces.
For some time now, SAP customers have been supported in system copying by very powerful automation tools that can be used as needed, such as "Shortcut for SAP Systems". Nothing has to be installed in your SAP systems for this - no transport requests, no AddOns!
That's why post-processing is required.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
To do this, however, the tools must contain the object dependencies for SAP's complex data model.
