When setting up a Production BOM there is a Unit of Measure field on the header which allows you to select from the unit of measure table. However, when creating a production order and refreshing Business Central uses the Base Unit Measure as the unit of measure on the production order line.
Proposed change would be that Business Central uses the unit of measure from the production bom/active version instead.

I can confirm that BC (v23.2) still does not behave properly. Interestingly though, while debugging the code, I see that it firstly does populate the UoM with the UoM from the Production BOM! Also the calculation for Routings and Components is good. However, after all of this is done, it does one final thing: Forcefully places the Base UoM of the item on the PO-line, undoing everything it has already done right.
Scenario:
Version: NL Business Central 23.2 (Platform 23.0.15284.0 + Application 23.2.14098.14274)
An Item to be produced via a Production Order, with a BOM:
No. 1000012
Base Unit of Measure: PCS
Item Unit of Measure: BAG (100000x the Base UoM)
Production BOM No.: PRB210008
A Production BOM:
No.: PRB210008
Unit of Measure Code: BAG
A Released Production Order for item 1000012:
No.: PRO00000018
Source type: Item
Source No.: 1000012
Pressing the Button “Refresh Production Order” creates a Production Order Line for Item 1000012, but with Unit of Measure Code ‘PCS’, which is the base UoM of the Item, even though the Production BOM that is used has the Unit of Measure Code ‘BAG’. Manually changing the Unit of Measure Code in the line yields the expected result, also in the Components.
Debugging the process shows that the PO Line firstly gets filled with the expected UoM ‘BAG’, but later it get filled with the Item’s Base UoM. This seems, at it’s minimum a waste of efficiency, but I think it’s a bug.
I've had contact with MS support, but I only get referred to this Idea. I don't thing we should be needing to vote to fix bugs?

A distinct planning unit of measure, much like sales UM and purchase UM, would be ideal.
I have a database full of finished good items with a base UM of 'case' and an each UM that is some fraction of a case and where those fractions are repeating decimals it's a constant problem.
The planning worksheet should look at the Production BOM UM and not the Item Base UM.

Thank you for this suggestion! Currently this is not on our roadmap. We are tracking this idea and if it gathers more votes and comments we will consider it in the future. Best regards, Business Central Team
