Role Approval Button in GRC BRM

Hello to all,

I have configured the workflow SAP_GRAC_ROLE_APPR, such that I can insert the role BRM. The role is sent for approval, through a Standard workflow Job. Unfortunately, unter the "other Actions" button, there is only "information requirement". The role Needs to be approved by a button here, I cannot find this button. Why cannot the user approve the workflow?

thanks

Ilona
