Transaction Code Description
A Conflict Resolution Transport (CRT) is used only for add-ons, such as IS-IS or IS-OIL. It is used to eliminate conflicts that may arise between the different support packages and an add-on. Note that a CRT that applies to an add-on release also resolves all conflicts with previous releases of that add-on. In addition, a CRT may include other corrections for the corresponding add-on. A CRT can therefore always be a special add-on support package. Settings for SPAM With Additional Settings, you can access a dialogue box where you can specify general settings for the SAP Patch Manager (SPAM). These settings affect the behaviour of downloading and loading support packages of the different types equally. SPAM updates are an exception; certain settings are specified for these. You can toggle the following properties on and off: Transmission Monitor If you enable the Transmission Monitor, you can monitor the download of the support packages from the SAPNet - R/3 frontend with a graphical monitor. Otherwise, you will only get a progress bar. Scenario Choosing the scenario determines which actions should be performed while the Support Packages are being played in. The default scenario is used to fully deploy support packages; All steps are performed. The test scenario allows you to determine whether a modification match is required or whether conflicts occur that should be resolved before the support packages are loaded. The test scenario does not import data and objects into your SAP system. There is no test scenario for SPAM updates. The choice is ignored when a SPAM update is introduced. Rebuild data files You can specify whether the data files from the EPS packages will be reunzipped each time you try to play. In principle, this is the case.
The security of an SAP system requires protection against unauthorised access, e.g. through the secinfo and reginfo files. A cleanly implemented authorisation concept protects against attacks within the SAP system. However, it is also possible to attack your SAP system via the network. Through the RFC Gateway Server, your system communicates with external servers and programmes. One particularly effective way to protect against this are so-called Access Control Lists (ACL). Find out what this is and how you can use it to better protect your SAP system. The SAP Standard offers different approaches for gate protection. All methods combined can provide even greater safety. For example, it is possible to use Access Control Lists (ACL) to monitor exactly which external programmes and which hosts can communicate with the gateway. Another option is to configure the gateway to support Secure Network Communication (SNC). Finally, there are various security parameters for the gateway. This article focuses on the use of ACL files such as secinfo and reginfo files. What is an ACL? Access control lists are files in which permitted or prohibited communication partners can be recorded. For the gateway to use these ACL files, parameters must be set in the default profile of the SAP system and of course the files must be maintained accordingly. With the help of logs and traces, which can be configured for this purpose, a precise investigation can be made in advance of the activation, which connections currently run via the gateway. This allows them to prevent important applications with which your system communicates from being blocked by the ACL files. The rules in the ACL files are read from top to bottom of the gateway to decide whether to allow a communication request. If none of the rules matches the requesting programme, it will be blocked. Network-based ACL The network-based ACL file contains permitted and prohibited subnets or specific clients.
In addition to proactive monitoring to prevent possible errors or even complete system failures, our SAP Basis team also implements clearly defined authorization concepts. So that unauthorized persons cannot access important data and your employees are protected from unintentional violations.
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.
The Queue determines which support packages are inserted into your system in which order by the SAP Patch Manager. If the queue is not yet fully defined, you must define the queue from the available support packages. If the Queue is already fully defined, it is only displayed; they no longer have the ability to change the selection. However, you can delete the queue completely with Queue [page 37]. Note that your system is inconsistent when you delete the queue after objects have been imported (for example, after an error in the DDIC_IMPORT step and following). The deletion in these SPAM steps should only be used for troubleshooting and you should repeat the insertion of the support packages as soon as possible. The SPAM transaction ensures that only support packages that match your system are displayed in the queue. Support packages intended for another release or an uninstalled add-on will not appear in the queue, even if they are loaded into your SAP system. For more information, see Rules for the Queue [page 19]. You must define the queue before you insert support packages. Prerequisites You have loaded the appropriate support packages with the SPAM into your SAP system [page 15]. Procedure To define a queue, select View/Define SPAM on the entry screen of the transaction. The Select Component dialogue box appears. You will see the list of installed software components (e.g. SAP_BASIS, SAP_HR, SAP_BW, Add-On). Select the desired component. You see the available queue. This queue contains the support packages available for the selected component in your system, and any required Conflict Resolution Transports (CRT), as well as associated Add-On Support Packages. You can: If the queue you see matches your wishes, you can accept the queue with Queue confirm and leave this selection window.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
Furthermore, it includes some administration tools and middleware programs.
The freeware Scribble Papers is a "note box" in which all kinds of data can be stored. It takes in typed texts as well as graphics and entire documents. The data is then organised in folders and pages.
For example, administrators define requirements and standards, select and control upgrades or enhancements, implement monitoring processes, and take care of necessary backups and emergency management.
