This is a general list. There are many other tasks that a basic consultant has to deal with. Every day you learn something new!
In order to reduce the variety of different system variations and the related variety of routine tasks, it is necessary to reduce the number of customer specifications. In particular, the implementation, set-up and configuration of the systems and security concepts must be harmonised or returned to the SAP standard. To this end, it is necessary to establish, in cooperation with the relevant IT departments, a standard for, for example, operating systems and databases within the limits set by the product.
RECOMMENDED GATEWAY SETTINGS FOR RFC SYSTEM PROTECTION
If your system is already above SAP NetWeaver Release 7.0, then you must either import SAP Note 1731549 or a corresponding Support Package. Afterwards, when creating new users, it is no longer possible to assign user names that are only composed of variants of spaces or other invisible special characters. Important: Changes to already existing users with these names or their deletion option are not affected by this! The SAP Note also adds the customizing switch BNAME_RESTRICT, whereupon you can control yourself whether alternative spaces are allowed to appear in certain places in the user name. For this, the following values must be set in the customizing table PRGN_CUST: NO = The alternative spaces are still allowed in the user name. ALL = The character set is reduced to a defined range, excluding certain special characters because they have specific meanings in certain operating systems or databases. This predefined character set is: ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789,;-§&()={[]}+#. FME = The letters F, M and E stand for Front, Middle and End. With an 'X' in this three-digit switch value you can now explicitly specify at which position in the user name no wide spaces and control characters may occur. All combinations are possible, e.g.: XME = None of these special characters may occur at the BEGINNING of the user name. XMX = In the user name none of these special characters may occur at the BEGINNING and at the END. FME = One of these special characters may occur at any position in the user name (this corresponds to the default setting, i.e. as if no entry was maintained in PRGN_CUST for the switch). SAP recommends the use of the value ALL.
You can reduce the Queue selection. To do this, select the Support Package that should be the last in the queue. After that, the queue is recalculated. You can also start the recalculation explicitly with Queue. Note that you can only select Support Packages that are part of the software component you have selected (the mouse cursor will change its appearance accordingly). The support packages associated with the calculated queue are green. The highest support package of the previously selected software component is additionally marked with a green tick. The support packages that are no longer part of the queue are still visible in the list and can be selected again. If you want to set the queue for another software component, select New Component. Result You have defined a queue. Now insert the support packages in the queue [page 20]. Rules for the Queue The following rules apply to creating a Queue: If it is an FCS system, the first step is an FCS Support Package. If it is missing from the queue, it cannot be defined. Instead, you will receive an error message telling you the name of the missing FCS Support Package. You cannot insert an FCS support package in a non-FCS system (official state of delivery). Support packages for a selected component are queued in order. If support packages in the queue have connections to support packages of another component (further predecessor relationship, required CRT), the queue will be extended by additional support packages until all predecessor relationships are fulfilled. Note that the SAP Patch Manager takes into account the configuration of your SAP system and only adds support packages to the queue that can be inserted into your system.
