Hi
I had the same issue. I raised it with SAP through OSS and had this response:
Hello,
Thank you for contacting SAP Global Support.
I checked the issue in
your system and found that during runtime the
system will check if a Switch
is active. This switch is
CRM_MKT_PRODUCTIVE1. Now this switch belongs to
Business Function
CRM_MKT_PRD. So if you activate this business function
this switch
will also be activated.
After activating CRM_MKT_PRD the Business role assignment is visible in our system.
Best regards
Mike
