Good morning,
I am doing this activity by pivoting my module.
With P3 SKU and account set up as default ( Nutzo bar EN and Candyate), i can flag or unflag the "override?" check box.

Then I want to set up as the activity asks me but the checkbox of override? disappears, and cannot set up final forecast at 71

Is there any explanation about the issue I have?
Or I have to do it in another way?
Thank you in advance
Arthur
