A dotted half consists of six eighth notes, so it should not normally fill a 9/8 measure. It would fill a 6/8 measure.

Michael Hillman,

Also, a dotted half normally fills a 3/4 measure.

Perhaps you have triplet eighths in a 3/4 measure?

Or perhaps multiple, simultaneous time signatures?

Could you attach a picture/scan of the music you are trying to copy?

I realize that. However in some older music they used a dotted half. I wanted to be consistent with the composer, Blazhevich

I guess the only way is to hide the rest.

Enter the dotted half as a tuplet, 9 eighths in the space of 6 eighths, and edit the definition to show no bracket or number. But keep in mind that it might just have been a lousy (or a lazy) copyist!

You could use an independent time signature via Staff Style as well.

Also what Mike R. said. If you aren't getting paid to copy it exactly as that old score, there's no benefit to doing it that way.

I don't believe it was a mistake. I think it is a stylistic thing in older music. (I may be wrong, but I have seen it before). Either way the easiest way to do it I think is to let the dotted quarter rest show up and then hide it. 

Thanks for the help guys.

What Mike R said. You can use the plugin «JW Rhythm Copy» to apply the rhythm after you’ve entered it once. Just enter one single eight note in those measures, the plugin will do the rest (!) for you.
