Introduction & Best Practices
What to do when the auditor comes - Part 1: Processes and documentation
In the course of a comprehensive protection of your system from the inside as well as from the outside it is indispensable to have a closer look especially at the SAP standard users. They have far-reaching authorizations that can cause great damage to your system if misused. It should be noted that they are very important for the operational execution of your SAP system and must not be deleted. However, since the associated standard passwords can be quickly researched, they must be changed immediately after delivery of the SAP ERP. You can perform a detailed check of these users using report RSUSRS003. It is also recommended to set certain default users inactive until they are actually used.
It is important that, if necessary, the database is converted to an SAP S/4HANA database. In addition, various technical system components must be analyzed and adapted to the new environment. But restructuring must also be carried out at the organizational level. For example, the "old", or current, authorization concept must be analyzed, evaluated and, if necessary, fundamentally revised.
Analyse and evaluate permissions using SAP Query
Excel-based tools that do not use the PFCG transaction in the background, like eCATT, function almost exclusively on the one-way principle: Simultaneous maintenance of roles in the PFCG transaction is no longer possible, and changes there are overwritten by the tool. This means that all permission administrators must work exclusively with the new solution.
Balance: In the settlement transactions, the user is only presented with the supporting documents for which he or she has permission. If the Profit Centre field is not filled in the journal view (Table BSEG), the general ledger view (usually Table FAGLFLEXA) is checked. To compensate, we recommend that you include the Profit Centre in the selection fields of the balancing transactions.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
In this context, we would like to give you some more information in this tip.
On the other hand, you can implement medium (3) and low (4) security advisories via support packages, which you should also include regularly.
