Orders: Costs and Allocations - Estimated costs (0CO_OM_OPA?)

Hi,

I am using the extractor 0CO_OM_OPA_1 to extract plan, actual costs and quantities that were posted on the internal order.

But I need extract the Estimates costs from IW33 t-code and this extractor dont have this information.

Somebody know where i can extract this information?

Thanks a lot
