Yes. You can enter as many expected additions as you like on the same production code, both positive and negative.
How to do it
Open the production code and choose the Expected Addition tab.
Click Add and enter a new item when you discover a new deviation.
Write a short description of what the item concerns.
Click Confirm.
Good to know
If you enter a new item instead of overwriting the old one, you keep the history. You can see, for example, that extra masonry work came two months later.
Negative items can be used to simulate an expected saving.
Make sure you do not enter the same deviation twice.
