BOM Component Code

[bcbnine]

I am trying to get just the valve coded to show up in the BOM under the component code which I have successfully done. However, the other components have a _# in that section. In the spec, I enter the valve code in the PIECE_MARK and I leave it blank for all the other components. Please see the attached ZIP file for a test iso I have been running.

Can anyone help me get rid of the _#?

Thanks,
Blake
