What is Table name for CJ40 unit costing data of WBS element

Hi,

I am looking for table, where the data is storing for "UNIT COSTING" data of a wbs element.

If we open an Project in CJ40 and by selecting a WBS element we can do its unit costing by pressing 'F7' or selection from application tool bar.

A screen opens with table control to create items for this WBS. but where this data is storing.

Thanks.
