Hi,
You can use the below query to find the correct table for the cost plane slices. Use the second query to find all the tables that are associated with cost.
Select *
from PRJ_BLB_SLICEREQUESTS SR
whew SR.REQUEST_NAME = 'costplandetail::cost::segment'
Select *
from PRJ_BLB_SLICEREQUESTS SR
whew SR.REQUEST_NAME like '%cost%'
