Authorization concepts in SAP systems
Handle the default users and their initial passwords
The authorisation trace is a client- and user-independent trace. The results of this trace are written in the USOB_AUTHVALTRC table and can also be viewed in the STUSOBTRACE transaction by clicking the Evaluate button. This trace data can be used by developers to maintain the permission proposal values in the transaction SU22 (see also Tip 40, "Using the permission trace to determine suggested values for custom developments").
Wildgrowth of characters used in user IDs can have negative effects. Set a bar on it by limiting the character set in the first place. In the SAP system, depending on the release of the SAP_BASIS software component, you can create users whose names may contain "alternative" spaces. In Unicode systems, there are different spaces, which are represented by different hexadecimal values. The usual space has a hexadecimal value of 20, but there are alternative spaces (wide spaces), which can be recognised, for example, as double width or not at all as character spacing. You can use these alternate spaces when entering the user ID by pressing the Alt key. For example, the key combination (Alt) + 0160 can create a space with a non-breaking space. You can also create a user whose ID consists only of alternate spaces. Users with such IDs will write all change documents, but the IDs can still cause confusion if, for example, they are not recognisable as a user ID or if it appears that no user is displayed for the change document. In addition, certain special characters may cause problems in other applications (e.g. in transport management). Therefore, we will show you how to prevent such problems by limiting the character set.
Authorization roles (transaction PFCG)
For result and market segment accounting, you can define planning authorization objects, the information system, and item-based reports of the information system. In the customising (transaction SPRO), you create them via the following path and then select the corresponding section. Controlling > Income and market segment calculation > Tools > Permissions management > CO-PA specific eligibility objects.
An SAP authorization concept is used to map relevant legal standards and internal company regulations to the technical protection options within an SAP system. Authorization concepts are thus the key to optimal protection of your system, both externally and internally.
