Our factory was nearly out of stock because production orders had been created with a BOM not having all cost prices calculated. The order was not reflecting demand for underlying parts of the BOM. For scheduled orders it looked like although we are not sure as we fixed the cost price issue. A route detail was not setup properly and no cost prices had been calculated. it was hard to discover where the problem exactly was:

Please improve:
- warn user that data is incorrect and might lead to wrong planning data; provide a warning that there are production orders not working together with MRP; unclear if created production order or missing cost was issue..or missing group on route detail;
- provide more information on errors generated during cost price calculation (cost category operation no 140 missing is not very helpful as operation no 140 cannot be found in a BOM with phantoms and multi levels);
- improve the product information --> released products field as it says no cost price, but it parts do have a cost price per site. We have 2 sites setup.
