How to get Table no. from a RecordID field - NAV 2016

Hi Folks -

In the Job queue entry table in NAV 2016 field no. 15 Record ID To Process is of Data type RecordID, I need to extract the Table No. from this field. I tried Recref.get(jobqueueentry."record id to process") but cannot figure out how to get the Table no. from here.

Any help is highly appreciated.

Thanks
RJ.
