Hi Vipul Vyas
I looks conversion step seems to be stop with incomplete status.
So to activate a cube and go futher, you need to reset AGS_RI_BPA_CUST.
But I cannot guarantee the all the step, so To be a safe side (I mean SAP official instruction), I recommend you to create SAP customer incident, and get official replay though the incident.
Best Regards
