Bypass Excel-based Permissions Traps
Permissions with Maintenance Status Changed or Manual
We recommend that you implement all safety instructions of priority very high (1) and high (2) directly. On the other hand, you can implement medium (3) and low (4) security advisories via support packages, which you should also include regularly. If you are unable to insert a support package at the moment, SAP will also provide you with the priority 3 and 4 security advisories. For the evaluation of the security advisories, you should define a monthly security patch process.

The first line defines that access to all files is forbidden unless other settings have been made for them in the other lines. The asterisk (*) is in the first place here and in this case for all files and paths. If the asterisk is in a different position, it is interpreted as part of the file name, which is not allowed in Microsoft Windows, for example. In our example table, setting the switches FS_NOREAD = X and FS_NOWRITE = X for all paths prohibits reading and writing. This makes the table a white list. This is preferable to a black list for security reasons. SPTH, on the other hand, becomes a Black List if you remove the first line with PATH = * in our example or if you do not set any of the switches FS_NOREAD, FS_NOWRITE or FS_BRGRU. The second line with PATH = /tmp allows read and write access for all files starting with /tmp, similar to a permission value /tmp*, as an exception to the access ban defined in the first line for all files and paths. This setting is not limited to subdirectories, but includes, for example, all files whose name starts with /tmp-xy. The third line with PATH = /tmp/myfiles defines a permission group with FS_BRGRU = FILE, triggering the subsequent permission check on the S_PATH object. The SAVEFLAG = X switch defines that these files will be included in a backup procedure; however, this is not relevant for the permission award.

For each area, the connection to other modules is the first priority. For example, for the Controlling division, the connection to the Finance division is first established by connecting the accounting area (FI) to the cost accounting area(s). The assignment of the cost accounting area to the result area is then an internal allocation within the controlling. If no allocations are found for certain valid organisational values, one of the two modules or the relevant functional area shall not be used for the organisational units of the enterprise.

In line with the maintenance of the SAP transaction permissions proposal values using the SU22 and SU24 transactions, it is advisable to maintain proposed values for web applications. In order for a user to be assigned a suitable rating for an operational feature set in the Web application, the software developers in the transaction SU22 must connect all the authorization objects required for this application to the corresponding Web Dynpro application, i.e. not just S_START. The source of the required authorization objects is usually a developer or permission trace.

However, if your Identity Management system is currently not available or the approval path is interrupted, you can still assign urgently needed authorizations with "Shortcut for SAP systems".

The Organisation Level Value Helper (Orgebene) provides a list of all customer-specific organisation fields, because only these can be converted back to normal Permissions Object Fields.

You can also find some useful tips from practice on the subject of SAP authorizations on the page www.sap-corner.de.
