P512000 - Job Status Inquiry Screen

Hello

I am trying to see if I can change the length of the ACCOUNT DESCRIPTION (DL01) to 30 characters on the screen in the Job Status Inquiry screen.

I looked at Processing options in P512000|ZJDE0001 version but could not see where I could do it.

I also see that there is a "column version " that is being used.. Where do I go to set up/modify this column Version?

Thanks
