PS report remainder no detail

in report S_ALR_87013558, under one investment program and WBS element, we can see details of budget/actual/commitment,

but under RemOrdPlan column, it shows total of 233390 USD, we drill down to the network level, but every network/activity level for RemOrdPlan is zero, how can I know the details of 233390? which table can i use to find valuation type 25, which defined Remordplan?
