You cannot enter inventory item costs. They are posted at current average cost, which can vary. Non-inventory costs can already be entered.
When creating a production order, it is only possible to see the name of the material that I place in the production process and nothing more. This greatly complicates the creation of a production order. I have to return to the warehouse every time to see the other necessary elements when calculating the cost price.
It would be desirable that in addition to any added items of material, at least those elements that are defined in the material warehouse are shown. This would make it easier to calibrate the cost of the cost of the planned product.
