After changing Purchase As UOMs for an item, the cost in the BOM is not correct


The cost of my BOM is not showing correctly after I made changes to the Unit of Measure for an item. 


For the Unit of Measure set to take hold in a purchase you will need to make sure that the vendor for that item is showing on the items vendor list. The cost for that Item to the vendor must also be included. 

Then the item must be edited to show that the standard cost of that item is what you will charge customers for that item.
