minimum set of roles for user

Hi,

I want to have a Fiori User with a minimum set of roles.

For my example I use the Fiori APP  "Create Purchase Order From Requisition"

So I created a new User and gave the user the following rights:

ZSAP_UI2_USER_700 --> Copy of  SAP_UI2_USER_700 with Authorization Objects ( see screenshot below)

ZSAP_MM_BCR_BUYER_X1 -->  Copy of SAP_MM_BCR_BUYER_X1 with "R3TR IWSG ZSRA013_PO_FROM_PR_SRV_0001" --> the name of the ODATA Service (like descriped in the SAP help)

ZSAP_MM_TCR_T_X1  --> Copy of SAP_MM_TCR_T_X1 - nothing else done.

Within the BackEnd the user has SAP ALL and all the BackEnd roles he needed - for me the Gateway and Fiori Part is important.

When I login with the "limited Testuser" I can only see icons with an crossed out eye:

What else is missing? Do you have any idea? I have checked the docu but found nothing else. With our "full blown" (Admin User) test users everything works fine! We are using GW on a NW 7.4

Best Regards Dominik
