MSMP workflow with both Roles and Systems as Lineitems

Hi Consultants,

So far i have created all my workflows with roles as lineitems and since roles are assigned to the system based on that all provisioning and de-provisioning used to happen.

Now client wants that access request should also have system lineitem to be included. In that case my workflow should validate system lineitem separately and roles line items separately. In this case do we need to go for FM based BRF+ rules ? I have not worked on them. If anyone implemented this scenario?

Kindly provide your inputs.

Thanks in advance.

Regards,

Madhu.
