Progress DB - Index on user define field

In a customization, I added JobHead.ShortChar02. - which is used to put the Job Number of where the lower level untested PWB is being produced. When I link the shorchar02 to the Job table in a BAQ - it is extremely slow. Is there a way to indexed a user defined field?

You can get to indexes in data administration
But… I’ve never added any indexes myself.
I’m not sure if you need a custom shortcut to launch data admin when you’re changing things.
Seems like I remember an old answerbook on EpicWeb that described the shortcut setup.
i.e. open in “Write” mode.

Thanks for giving me a start -
