General authorizations
Starting Web Dynpro ABAP applications
SAP*: The SAP* user is part of the SAP kernel, and since it is hard-coded in the SAP system, it does not require a user master set. If there is no user master set for SAP*, anyone can log on to the SAP system after rebooting with this user, as the default password will then apply. The user thus has access to all functions, since Authority Checks in this case do not take effect. You can prevent this behaviour by setting the login/no_automatic_user_sapstar profile parameter to 1. If you want to copy clients, you have to set this parameter to 0 again before you do so, because the user SAP* is required for this. Safeguard measures: Despite the parameter setting, the SAP user should have a user master set in all clients. However, you should remove all profiles and lock the user. In addition, change the password, assign the user to the SUPER user group, and log it with the Security Audit Log.

The role menu of the PFCG role now consists of folders that represent all logical links within a scope start page, and external services that represent the logical links and the area start pages themselves. This means that any external service listed in the Role Menu is eligible for a Area Start Page or Logical Link. If such an external service is removed from the role menu and the PFCG role is generated, the user of this PFCG role does not have permissions to view this external service (see screenshot next page). You will find duplicate, maybe even triple, entries from external services. These are mainly found in the folders of the homepage and under GENERIC_OP_LINKS. You can delete them without any concern, because an external service for a permission must appear only once in the Role menu. For a better overview, it is also useful to rename the external services or folders as they are shown in the SAP CRM Web Client.
Background processing
Now, if you want to use the debugger, you can set a Session Breakpoint directly from the source code via the button. Once you call the application and reach the relevant point in your code, the debugger starts and you can move through the programme step by step. Make sure to set external breakpoints via the button if you are calling your application via the browser rather than via SAP GUI.

The website www.sap-corner.de offers a lot of useful information about SAP authorizations.

If you want to export the movement data of the productive system to a development system, you should first export user master records and the permission proposal values and archive the complete change documents. After importing, you can then delete the imported change documents, in analogy to the client copy, and then reload and index the original change documents of the development system. The activities described here require administrative permissions for the change documents (S_SCD0 and S_ARCHIVE) and, if applicable, for the table logs (S_TABU_DIS or S_TABU_NAM and S_ARCHIVE). These permissions should be considered critical, and you should assign them to a small circle.

Authorizations can also be assigned via "Shortcut for SAP systems".

In this case, implement the required checks in the BAdI FI_AUTHORITY_ITEM.

To store all the information on the subject of SAP - and others - in a knowledge database, Scribble Papers is suitable.

When using encryption mechanisms, be sure to prevent access to the personal security environment (PSE) files in the server's file system and database.
