Query on Scheduling Organizer

Hello Team,

We have a requirement to update the Promise Date using the Scheduling Organizer screen in Order Management. However, we notice that although the Promise Date field is available, it is greyed out and not open for update.

1. Is there a way to enable this to make updates; alternatively is there a different screen from where the Promise Date can be updated.

2. The Sales Order Line level DFF is also displayed on the Scheduling Organizer screen, however this too is greyed out and is not updateable. Please advise if the DFF too can be enabled for updates.

Sample screenshot is attached.
