Suggestion:
The BOM costing report has selection criteria of BOM and pricelist. It shows the BOM which is of confirmed status and it should be active. Pricelist’s ‘Effective from’ date should be less than today’s date. The report will show details of all Items which are in BOM and which are defined in the pricelist whose effective date is less than today’s date.
BOM Costing report exists in Manufacturing -> Manufacturing report and Analysis-> Manufacturing reports-> Production -> Bom Costing
