Unable to file 1065 Partnership Return due to Business Code

[kzinsk]

I'm getting an error on my federal 1065 partnership return saying I haven't entered a valid 6 digit business code.  In all past years I've used 531100 for my rental property but that's giving me an error.  I read an article that this number doesn't effect your return, and is just used for data collection,  that you can enter 999999 instead.  That didn't work either though. Please help!

The business codes have changed. Use one of the codes provided in the instructions for Form 1065.
