Dear Jan Boeykens,
1.. If you want to calculate the Production cost for your manufacturing component you have to run the costing i.e. SCE
while running SCE system will explode the BOM and calculate the cost at each level
Product cost = Raw material cost + In process cost (As per Routing cycle times +KP26 Activities price)
here system will calculate the Production cost per piece.. once you release the cost it will update in material master
2.. when you create a production order system will refer the material master price according to that price system will calculate the cost of that production order
Production order cost = Production order qty * Material master price
According to your confirmation system will calculate the actual / planned price for that production order
if you want the cost for the production order you have to run costing i.e. if there is no costing then you can't be able to see the cost at production order level
Regards,
Venkatesh..
