Work center field greyed out in Quality Notification

Hi All

When i create a Quality notification from Defects recording screen, Work center & Plant for work center fields greyed out in the Notification in QM02.

But when i create notification manually with same notification type, the above said fields are editable.

1. Is there any way to make these 2 fields editable in QM02?

2. Also any possibilities to get these 2 fields populated with some default values from the Inspection lot?

Thank you.

Regards
