Hi guys and girls
I need help understanding a problem.
I have to create some work orders, to create my products, then … the flow is similar to:
The conversion is not behaving as expected:
The BOM items:
The Work Order:
The items must behave as the fist of the list. When I analise the second item:
Default Unit of Measure
Weight Per Unit
Conversion Factors
_Just cheking the math 
_
How can I make the BOM and the Work Orders have the same units?
An additional doubt:
How can I make the bill of materials and work orders have the same units?
An additional doubt:
When I have some historical purchases, I can not change the default UOM. Will I have to duplicate the item by changing its default UOM?
Example
And what should I do with the purchase history, stock movements …?
