Compensating measures for segregation of duties conflicts
Help, I have no permissions (SU53)! You want to start a transaction, but you have no permissions? Or the more complex case: You open the ME23N (show purchase order), but you don't see any purchase prices? Start transaction SU53 immediately afterwards to perform an authorization check. The missing authorization objects will be displayed in "red". You can also run SU53 for other users by clicking on Authorization Values > Other Users in the menu and entering the corresponding SAP user name.
Add SAP Note 1433352 to your system. This note ships with the RSAUDIT_SYSTEM_STATUS report. This report documents the current status of the Client and System Modification Settings in an overview, which you can also print out for evaluation if required. The advantage of this report is that pure display permissions are necessary to execute it.
Use usage data for role definition
If the proliferation has occurred because the authorization concept was not adhered to, a cleanup is sufficient. If the proliferation has arisen because there are errors and gaps in the authorization concept, these errors must be identified, eliminated and the authorizations optimized. If the concept can no longer be implemented in a meaningful way, or if it has already been set up incorrectly, it will be necessary to create a new one.
Due to the complexity of an SAP® authorization concept, it is necessary that all essential aspects are set down in a written documented authorization concept. This should describe the essential processes, but also how to handle the assignment of authorizations via roles. In particular, the nomenclature of specially created roles must be clearly defined. It should therefore be checked whether all changes since the last audit have been documented in the written authorization concept. After all, this document serves the auditor as a template for the so-called target/actual comparison. This means that the auditor compares the document with the actual status in the SAP® system for the main topics relevant to the audit. Any discrepancy can lead to a finding that must be avoided.
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.
To do this, use the SUIM_CTRL_CHG_IDX report without selecting a date and check the Reset Index box.
However, this should not be a topic here in the article.
