Several advantages at once
Consideration of additional QA clients
Depends on the extent of splitting and the degree of parallelization. When importing, the limiting factor is often the index structure.
Third-party tools sometimes have a different focus than TDMS. The tools each offer a more or less generally understandable user guidance and are thus "out-of-the-box" products that do not require external consulting on implementation or application.
SAP Landscape Copies
While homogeneous SAP system copy expects identical combinations of operating/database systems on the source and target systems, there is also a requirement for different combinations of operating/database systems on the source and target systems in the project environment (eg, during migrations). This is referred to as a "heterogeneous SAP system copy". Technically, it is quite possible to build up a degree of automation here as well, but officially certified consultants ("migration consultants") are required to perform the heterogeneous system copy.
For a heterogeneous system copy and for homogeneous system copies for which there is no special way for the database used, the source system must be exported. This is done with SAP tools (SUM). The export files are copied to the prepared target system and imported again during the SAP installation with SUM. A relatively comfortable way. But it can be even more comfortable.
With "Shortcut for SAP Systems" you get additional functions for the SAP system copy.
Table splitting reduces the risk of losing a lot of time during export in case of an error.
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 avoid having to repeat the customizing (settings and configurations of the SAP modules and business processes) on these systems, it makes sense to make a copy.
