Release date column permanently displayed in MD04

Good morning.

In MD04, you can display Release Date column and Opening Date column by draging (they are located next to "MRP element" column, you just have to put your cursor on the vertical separator until the cursor displays two lines and then drag on the right). However, this setting is not permanent; if i go out of MD04 transaction and come back in again, this column has dissapeared. Has anyone any idea of how i can make this column displayed permanently?

Best regards,

Nikos
