Set up permission to access Web Dynpro applications using S_START
You want to secure access to the application server files? Find out what the S_DATASET and S_PATH authorization objects offer, what limitations are, and what pitfalls are lurking. Access to the application server's files is protected by kernel-built permission checks, similar to how transactions and RFC function blocks are started. SAP's proposed permissions for the S_DATASET authorization object do not provide much help, and S_PATH has virtually no information, because you must activate this authorization object only by customising the SPTH table. Often the permissions to S_DATASET are too generous, the SPTH table is not well maintained and S_PATH is not used at all. Here we show you how these permissions work and how you can restrict them.
The permissions on database objects show you the details of the user's permissions to access the object. In the following example, the MODELING role includes permission to use the _SYS_BI object with the EXECUTE, SELECT, INSERT, UPDATE, and DELETE privileges. In addition, a user assigned this role is not allowed to pass these privileges on to other users (Grantable to Others). Our role as an example also includes Analytical Privileges and Package Privileges, which are not discussed here.
Check the SAP authorization concept
The specific SAP_NEW authorization object imprints are provided via the SAP_BASIS component. Therefore, an SAP_NEW profile is always bound to a specific base release. Proceed as follows: With the transaction SU02, you remove all old, individual profiles from the SAP_NEW composite profile, including the profile that belongs to the start release of your upgrade. Now assign the reduced SAP_NEW permission profile to all users in the upgrade preparation system, ensuring that all users can work as usual. This step can be omitted if you are following another method to identify missing permissions. Now check all permissions in all remaining profiles within the SAP_NEW summary profile that have a higher release level than the SAP_BASIS upgrade start release. Map all required permissions to all productive roles in your permission concept. You can do this for each intermediate release individually. The next step is to adjust the permissions in your productively used roles in the PFCG transaction, and then remove the corresponding permissions from the SAP_NEW profile using the SU02 transaction. Repeat steps 3 through 4 until the SAP_NEW permission profile is empty. Work in a development system during the role adjustment phase and transport the adjustments made to your eligibility roles to your quality assurance system. After successful acceptance test, you transport them to the production system. Now you can remove the SAP_NEW profile from all users. You can then proceed with role follow-up as part of the release change in the SU25 transaction (see also Tip 43, "Customise Permissions After an Upgrade").
Careful preparation is a prerequisite for a successful authorisation check. A functional specification must be created for all customer-specific functionalities. This forces us to think about what the actual requirements of the application are and then describe the possible implementation. In doing so, security-related aspects, such as eligibility testing and allocation, must be taken into account. Define what you can do with this programme and also what you cannot do explicitly! In the case of a permission check, not only the activity to be performed, such as reading, changing, creating, etc. , can be checked. You can also restrict access to records by using specific criteria, such as field content or organisational separators.
Authorizations can also be assigned via "Shortcut for SAP systems".
Suggested values are maintained in the transaction SU24 and delivered through the transaction SU22.
The website www.sap-corner.de offers a lot of useful information about SAP authorizations.
Some queries are also a bit complicated with the SUIM transaction.
