PROGRAM START IN BATCH
The concept for in-house developments is obligatory for every company that writes its own software. It specifies requirements, for example, for the structure, naming and documentation of program components, and in particular for dealing with safety-critical aspects. The wording should not be too general, but should explicitly address the special features of programming in SAP.
For the entries in the SPTH table, note that the application defines whether a file is accessed with or without the path. For example, the related transactions ST11 (error log files) and AL11 (SAP directories) behave differently. While ST11 opens almost all files without a path (they are in the DIR_HOME directory anyway), AL11 basically uses fully specified file names with a path. An entry in the SPTH table with PATH = / is therefore misleading. It specifies that the defined access restrictions apply to all files specified by path. However, this only applies to applications that access files using a specified path. However, applications that access files without a path are not restricted; Files in the DIR_HOME directory may be excluded.
The requirements in the third example to filter the Post Journal Display (transaction FAGLL03) can be implemented using the BAdIs FAGL_ITEMS_CH_DATA. Depending on the permissions granted, certain items or documents should be excluded from display. You can see the definition of BAdIs through the SE18 transaction, and in the SE19 transaction you create an implementation of the BAdIs in the Customer Name Room.
The SU10 transaction, as the user administrator, helps you maintain bulk user master records. You can now also select the user data by login data. You're probably familiar with this. You have blocked users, for example, so that a support package can be included. Some users, such as administrators, are not affected. For collective unlocking, you only want to select users with an administrator lock. The mass maintenance tool for users in the transaction SU10 is available for this purpose. This transaction allows you to select by user and then perform an action on all selected users. Until now, users could only be selected by address data and permission data.
For the assignment of existing roles, regular authorization workflows require a certain minimum of turnaround time, and not every approver is available at every go-live. With "Shortcut for SAP systems" you have options to assign urgently needed authorizations anyway and to additionally secure your go-live.
The other systems, including the development systems, must also be included in the risk considerations.
Assigning clear authorizations to employees is not a sign of mistrust, but offers a high level of protection - both for the company and for the employees themselves.
