INTRODUCTION OF RELEASE AND PATCH MANAGEMENT
When I began my career administering SAP ERP on Oracle in the early 1990s, running a database required far more knowledge. An Oracle administration expert with a decade of experience understood perhaps only about 5% of what the database required.
The decision to outsource a task or service should be taken not only in terms of cost, but also by assessing the competitive differentiation and strategic importance. Characteristics for describing the costs are the specificity of the task and the embossing by unit cost degression, i.e. decreasing costs with increasing number of tasks or performance. Of strategic importance are, in particular, those tasks and services which are difficult to imitate by competing companies. Figure 4 compares the strategic importance and cost advantages in order to arrive at fundamentally valid statements regarding the usefulness of outsourcing for certain IT tasks and services. In addition to this, as already discussed by Recommendation [A2], it is then worthwhile to establish a catalogue of criteria for evaluating and looking in detail at certain characteristics of the application or services. An exemplary catalogue of criteria can be found in chapter 9.6 of the Master thesis. Figure 4: IT Outsourcing Decision Matrix THE DECISION TO OUTSOURCE A TASK OR PERFORMANCE SHOULD BE MADE NOT ONLY IN TERMS OF COSTS BUT ALSO BY ASSESSING COMPETITION DIFFERENTIATION AND STRATEGIC IMPORTANCE.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.

SAP SE offers various training courses and certifications for SAP Basis administrators and SAP Basis consultants. As an alternative to internal recruitment and training, companies can also turn to external consultants or even outsource the entire SAP Basis administration to an external team with experience in SAP Basis.
Using profile parameters, we can configure everything in the SAP system. Some parameters are dynamically modifiable, which means that they can be changed without restarting the system. However, these changes are not permanent, i.e. after a system restart, the pre-set profile parameters are used again. Other parameters, however, are static, i.e. only with a restart and only permanently modifiable. Most profile parameters for memory allocation are actually static. However, there is the possibility to adapt it dynamically with the report RSMEMORY. Read how to find out if a parameter is static or dynamic and how to use the RSMEMORY report to dynamically adjust the memory allocation parameters. RZ11 - Maintenance of profile parameters The transaction RZ10 gives us information about profiles, which in turn contain different profile parameters. In the transaction RZ11, however, it is possible to view information about individual parameters, provided that you know their name. As you can read in our Memory Parameter Post, the following 5 parameters are particularly important for memory management: abap/heap_area_total abap/heap_area_dia abap/heap_area_nondia ztta/roll_extension_dia ztta/roll_extension_nondia If you don't know exactly what a parameter might be called, it's worth using the F4 help here. For example, for the parameter abab/heap_area_dia, the RZ11 outputs: Description of the parameter abap/heap_area_dia in the RZ11 As you can see here, it is not a dynamic parameter. Now it is rather sorry if you want to test whether there is enough memory available to restart the system again and again. For this purpose, there is the RSMEMORY report. RSMEMORY - Test your memory allocation strategy Report RSMEMORY Report View No documentation or value help available here, but SAP documentation tells you how to use the report. This first distinguishes between dialogue and non-dialogue work processes. That is, in the first area you can set Extended Memory (Storage Class 1) and Heap Memory (Storage Class 2) for Dialogue Workprocesses, and in the second area you can set it for non-dialogue workprocesses.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
Quite a lot of power! Did you also know that the SAP system provides a feature that deletes table change protocols (DBTA BLOG table) and that it is effective across all clients? If the table change logs have not been additionally archived via the BC_DBLOGS archiving object, traceability is no longer available.
So much information... how can you keep it so that you can find it again when you need it? That's what Scribble Papers is great for.
This prevents that just because someone would start a new chain, someone would accidentally recognise it as "reality".
