Users, roles and authorization objects
Certain authorization objects are required on the Backend and Frontend servers in addition to the application roles required for the specific FAB app. IQX has documented these for your reference. The authorizations may be implemented as recommended below or to your own role and naming convention using PFCG.
Implementing App-Specific FAB Authorisation /IQX/FAB
App-specific authorization can be invoked by the selection of the Authorization Checkbox on the Properties screen and providing a value in the Auth. Group field in the FAB Workbench.
This setting mandates checks to the FAB delivered authorization object /IQX/FAB.
Authorisation Object: /IQX/FAB (SU21)
Allowed activities:
01 – Create New Instance
02 – Change Instance
03 – Display Instance
04 – Delete Instance
11 – Workbench create
12 – Workbench edit
13 – Workbench display
Authorisation Group
Multiple values, free text entry, support wildcard entry patterns eg FI*
Sample implementations
Functionality | /IQX/FAB-/IQX/ACTVT values | /IQX/FAB-BEGRU values |
Ability to Create, Change and Display FAB instances for Apps having Authorisation Group value of FI | 01, 02, 03 | FI |
Access to create Apps in the workbench | 11 | * |
Access to Edit and Display in the workbench for apps having Authorisation Group value of SD | 12 and 13 | SD |
Activity 11 is the main authorization required for a developer to have access to create an app
from the workbench (TCODE /IQX/FAB). This is implemented in the role /IQX/CONFIG (Section
4.3.3)
FAB Generic User Roles
Assign to who: All users that will use the applications generated by FAB
Where to assign: All systems installed with FAB
Backend
Role Name: /IQX/END_USER
Authorization Objects defined for the role are:
- /IQX/FAB
- S_SERVICE
- S_PERSONAS
- S_RFC
- S_RFCACL
Further restriction to the authorization object /IQX/FAB can be implemented. Depending on the security/access requirement, the role can be implemented multiple times and in separate roles having different combination values for /IQX/FAB.
Role Name | /IQX/FAB-/IQX/ACTVT values | /IQX/FAB-BEGRU values |
/IQX/END_USER_FI | 01, 02, 03 | FI |
/IQX/END_USER_MM | 01, 02, 03 | MM |
Important
S_RFCACL (Trusted RFC) authorization value should be limited to the calling system which is the SAP Gateway system. Please refer to the SAP Note 1416085 for further details.
Services that users should be having access to, in addition to the /IQX/* services, must be added in the S_SERVICE authorization object values
Role template: IQX_END_USER.txt
Frontend
Role Name: /IQX/END_USER_GW
Authorization object defined for the role is S_SERVICE.
Important

FAB Developer / Cutover Roles (Install on GW and Backend)
Assign to who: Developers and consultants who will perform the configuration
Where to assign: All systems installed with FAB with a limited validity period in the production environment
Role Name: /IQX/CONFIG
The same set of authorization for Backend and Frontend systems. Critical authorization defined is /IQX/FAB and important TCODEs are /IQX/FAB, /IQX/FAB_CONFIG and /IQX/FAB_ANALYSIS.
The role has all activities for /IQX/FAB and this is the main reason why it should only be assigned for a limited period in the production environment.
Role template/upload file: IQX_CONFIG.txt
FAB Support Roles (Install on GW and Backend)
Assign to who: Users, usually developers/consultants, that will provide support in the Production environment
Where to assign: Production environment where FAB is installed.
Role Name: /IQX/SUPPORT
The same set of authorization for Backend and Frontend systems. Critical authorization defined is /IQX/FAB and important TCODEs are /IQX/FAB_CONFIG and /IQX/FAB_ANALYSIS.
Authorization for /IQX/FAB activity is limited to 03 (Display Instance) only
Role template/upload file: IQX_SUPPORT.txt
OneList Admin role
Assign to who: Developer in Dev/UAT environment, Support users, Administrative users that support in Production environment
Where to assign: All systems with OneList
Role Name: /IQX/OL_ADMIN
The role contains set of authorization to access the following transactions: /IQX/OL_CONFIG, /IQX/OL_ENDPOINT, SM30 with Auth.Group OLIS, SU53.
Role template file: IQX_OL_ADMIN.txt
Trust relationship, set up and testing using SM59.
For a Hub deployment, a trust relationship is required between the BE and FE servers. This enables communication between the two servers. The trust relationship is achieved by setting up the same user in both the BE and FE servers and then testing the connection using SM59. Refer to section 4.3.2.1 for details on the authorization/role implementation related to trusted RFC.
First of all, you will need to create a user (in this case IQX_FABUSER ) to use in the Trusted Relationship. This can be done in transaction SU01. Then, you need to assign the authorization object S_RFCACL to this user.
Refer to detailed documentation in this link: https://wiki.scn.sap.com/wiki/display/ABAPConn/Create+an+RFC+trust+relationship+between+2+SAP+systems+-+A+step-by-step+guide
Suggested RFC connection name set up in BE server using SM59. Choose your own RFC name and add suffix ‘_FE’. Set Logon and Security to Current User. In Technical Settings set Target host to FE server.
Suggested RFC connection name set up in FE server using SM59. Choose your own RFC name and add suffix ‘_BACK’. Set Logon and Security to Current User. In Technical Settings set Target host to BE server.
Do a Connection Test and a Remote Logon test.
