A bit unclear as to what you are actually asking.
Are you after a report of WORK ORDER WIP value ??
If Yes then the bad news is there is no standard available report (Pre8.9
anyhow).
You will probably have to have a report written.
If you use the WO number in the subledger field and have only a few WIP G/L
accounts then you could consider writing a WIP report based on G/L F0911.
Probably a better bet is to write report based on F3102 (Work order cost
file.) Here report can be based around Actual values less completed scrap
values. You can use data selection to limit to work orders at a certain
status, for a certain branch plant etc...
