Deleting table change logs
All external services for cross-navigation are stored in the role menu in the GENERIC_OP_LINKS folder. In addition to this information, this folder also contains external services that represent the already mentioned area start pages and logical links. You can delete the latter, as these are duplicates from the other folders or non-relevant external services. Now, to set up correct permissions for the non-manageable external services in the GENERIC_OP_LINKS folder, you can identify the external services you need for your CRM business role and delete all other external services. However, as I said, there is a risk that too many external services will be deleted and cross-navigation or calling the saved searches will no longer work. It is better to move the GENERIC_OP_LINKS folder to a separate role.
The security of an SAP system is not only dependent on securing the production system. The development systems should also be considered, since here it is possible to influence the productive system via changes to be transported in the development environment and in customizing or via inadequately configured interfaces. Depending on the conceptual granularity of responsibilities in the development and customizing environment, more detailed authorization checks may need to be performed.

The customising parameters in the table PRGN_CUST control the password generator in the transactions SU01 and SU10. The values of the profile parameters override the customising parameter entries to prevent invalid passwords from being generated. If the value of a customising parameter is less than the value of the corresponding profile parameter, the default value of the customising parameter is drawn instead. The same is true if no value is maintained. You can exclude certain words or special characters as passwords by entering them in the USR40 table. In this table you can enter both specific passwords (e.g. your company's name) and patterns for passwords (e.g. 1234*). '*' stands for any number of additional characters (wild card) and '?' for any character. However, when maintaining the USR40 table, note that the number and type of entries affect performance.
In the PRGN_CUST table, set the customising switch REF_USER_CHECK to E. This prevents you from using other types of users than reference users. This switch only affects new mappings; You should manually clean up any existing mappings of other user types.
