Setting up SAP functions
You can create function definitions, function instances, and variable sets for SAP functions. A function definition contains the authorization definition as well as general main data. An authorization definition contains at least one SAP application. Each SAP application belongs to at least one authorization object. Each authorization object consists of at least one function element (activity or authorization field) with concrete instances. Instances are given as single values or as upper and lower scope limits. Function elements can be listed more than once per authorization object.
You can use an SAP function for different instances. To do this, use variables in the authorization definition. Fixed variable values are grouped in variable sets and used in the function instances.

Create a function definition.
-
Create the authorization definition.
-
Consider the explanations for determining invalid authorizations.
-
Take the notes on authorization definitions into account.
-
Use variables for the values or scope limits if needed.
-
Check the completeness of the authorization objects.
-
(Optional) Assign mitigating controls to the function definition to be implemented when invalid authorizations are detected by the SAP function.
-
To be able to use the function definition for authorization checking, enable the working copy of this function definition.
-
Create at least one function instance for this function definition.
To find all the identities that match this SAP function through their SAP user accounts, apply the SAP function in compliance rules.

Creating function definitions
A working copy is added to the database for every new function definition. The changes are not passed on to the production function definition until the working copy is enabled. SAP authorizations are only checked on the basis of active function definitions.
To create a new function definition
-
In the Manager, select the Identity Audit > SAP functions > Function definitions category.
-
Click 
in the result list.
-
Enter the function definition main data.
-
Save the changes.
This adds a working copy.
-
Select the Authorization Editor task and set up the authorization definition.
-
Select the Enable working copy task and confirm the security prompt with Yes.
This adds an enabled function definition in the database. The working copy is retained and can be used to make changes later.
