SXMS_PF_AGGREGATE report taking long time to execute

Hello Experts ,

I have scheduled SXMS_PF_AGGREGATE report in background since long(around 20 days) but it has not finished yet . When i check the job log , it says n number of aggregates created so far. That means it is working . But i want to know when it will be finished ?

Thanks in advance.

Regards ,
