Redesign of SAP® Authorizations
Introduction & Best Practices
In the area of group consolidation, an authorization concept ensures that no data can be deliberately manipulated, for example to change balance sheets. This can prevent significant financial or reputational damage to banks and stakeholders. Furthermore, access to financial data of subdivisions of a group, such as individual business units or companies, must be restricted to those employees who are allowed to access it because their current activities require it. As a result, a controller of a business unit, for example, can only view the consolidated figures of his business unit, but not the figures of the entire group. Further authorization roles are required, for example, for external auditors. These auditors check all the figures for the entire group, but may only have read access to this data.
Here, the authorizations are either derived from the role menu (through the authorization default values (transaction SU24) or can also be edited manually in expert mode. The individual authorization objects are divided into object classes. For example, the object class AAAB (cross-application authorization objects) contains the authorization object S_TCODE (transaction code check at transaction start) with the authorization field value TCD (transaction code).
Important components in the authorization concept
In our example, the end user logs on to an SCM system, but can also call ERP transactions from here. To have these ERP transactions available in SAP SCM, create a new PFCGE role in SAP SCM, e.g. ZS:XXXX:ERP_MENU. The ERP transactions that the user should have access to are added to the roles menu by selecting Apply Menus > From Other Role > Destination System. Now select the appropriate ERP system and then select the appropriate PFCG role from SAP ERP. You do not need a profile for this "menu role" because this role only includes the ERP menu. You can now sort the transactions in the Hierarchy pane by using drag and drop or by using the arrow keys as you need them in the NWBC.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.
At "www.sap-corner.de" you will also find a lot of useful information on the subject of SAP authorizations.
This additional filter logic works as follows: The first step is to check whether the user is entered in the tax verifier table (Table TPCUSERN, Configuration with the transaction TPC2).
