Custom Attribute Mapping 
You have created custom attributes.
On the SAP MII administration menu, choose
On the Users or Roles tab page, select the user or role to which you want to map a custom attribute.
If you are mapping a custom attribute to a role, select a priority for the role.
The system applies the attributes of the role with the lowest priority (0) last. If you are assigned to two roles with the same attribute, the attribute value from the role with the lower priority is used.
Select the attribute and click Add.
The custom attribute is added to the table.
Enter a value.
If a default value appears, you overwrite it.
To delete a custom attribute from the table, click the attribute row to select it and click Delete.
Click Save.
You create the custom attribute Color, select it as required, and enter a default value of Green.
You map the attribute to one of the following roles:
Role1
You select a priority of 1 and enter a value of Blue.
Role2
You select a priority of 10 and enter a value of Red.
A user who is not assigned to Role1 or Role2 logs on to the system. The Color attribute value for this user is Green.
A user assigned to Role2 logs on to the system. The Color attribute value for the role overrides the default value, so this user's value is Red.
A user assigned to Role1 and Role2 logs on to the system. The Color attribute value for the roles overrides the default value, and Role1 has a lower priority than Role2, so this user's value is Blue.
