Steps to reproduce the bug: - Create three stockable products P1, P2, P3 - Create a BOM for P1 with P2 and P3 as components - Create a MO with 5 P1 - Check the availability and plan it - Go on the WO and process only 3 P1 - Go to the MO and update the quantity to 3 Bug: From this point, it was impossible to pass the MO to the state= 'done' With this fix, you can now, click on "Post inventory" and the button "Mark as Done" will appear. opw:1874227
