Hi gurus ,

Please help in the followoing scenario

For any production order : GOTO > Costs>Itemization : it says Planned values are recalculated

  At which table level we would retrieve the Itemization details for any production order(containing Material).

The requirement is to develope a report to display the Cost Itemization details for any production Order.

Any help is appreciative or helpful.
