So in the image below I have a weldment part and a BOM. The BOM I created in the part file then linked it to the drawing file, when I auto ballooned the two views it did not balloon item 1.4 or 1.5. These two parts are both hidden in the front view but in the right view 1.4 is visible. What did I do wrong?
Well, I think that the easiest thing to do is to create the BOM in the drawing, and link the BOM to the right view rather then the front view. Then inside the front view's properties, use the BOM you created from the right view.
edit: 
That worked, but I think I left out that part 1.5 is still hidden in the front and right view's, it would only be visible from the back view which I didn't want to show. Unless theirs another way I can just take the time and create an explode view. Thanks for taking the time to help.
I would keep myself away from ballooning any hidden components. I would rather add another view like section view or broken out section to show the components and balloon them.,
If you mean Hidden as in behind something you can't see in a view, I'd do a stacked balloon with the first attachment being the component you can see and then hide that component from the view and then update (add to the balloon stack) the other hidden files.
I have one connector hidden in the view so I could attach the balloon (stacked) to the contact of this cable assembly.
Hope this helps...

To answer Steve's question, yes I do mean hidden behind something or out of site. So what I did was sort of what Steve suggested. I went back to the model and selected the body (1.6) that was covering the body (1.5) I wanted to balloon and then Hide the body from the model and rebuilt the drawing and ballooned part 1.5. Then I went back to the model and chose to show all hidden bodies, rebuilt and then ballooned part 1.6. 
Is this an except able way to show there's another body behind 1.6?
In my opinion, no....this will cause confusion.
Can you add a broken out section to one of those views to show the part? Even better would be an exploded view or a section view like Deepak suggested.
Zach, you don't have to go back to the model/assembly to hid and un-hide the components. You can do that right from the tree in the drawing.
I have no problems ballooning to hidden parts because I have a PDM system and it will add the balloons to my BOM there.

Hi Zach,
This thread might answer your question 'Part Number on Far Side'. I asked something similar a few years ago and now use the suggested answer by Wayne.
I also have the box around the part No show as dashed so we know the part is on the far side (Hidden).
Thanks

Zach,
When placing a balloon RMB while the cursor is hovering over the hidden part and click on Select Other.
Just select from list.
IMO - Marking hidden objects would make a huge confusion in our shop, I would add more views, section views and or detailed views.
I fail on this, but - A drawing done properly will convey to manufacturing a detailed way of making a final product and if this is done without any questions to the designer/layout person, then the job is done correctly.
So, to add to your comments, John, I agree with ballooning hidden objects for the "floor" isn't the best practice. My cable drawings are used outside the shop at several suppliers and as long as they have the BOM they have no troubles.

I agree with John,
if manufacturing has to ask any questions, then either they haven't been trained properly or the designer/drafter failed. All information relevant should be on the print.
I am with you John Stoltzfus, I fail on this from time to time as well. That is why we need good drawing checkers.....drafters/designers need a good accountability system......just like we do in life.
The only time I'll balloon hidden parts is when ballooning a stack of hardware. I occasionally attach the first balloon to the bolt, then add stacked balloons for the washers and nut. And I don't need to hide any components to do that. I just set the view to "Hidden Lines Visible", which lets me see the edges of the hidden parts to link the balloons to them, then switch the view back to "Hidden Lines Removed".
Having stacked hardware such as Bolts, Nuts & Washers is one thing and would be acceptable in a lot of places, but a pc of a weldment, that you can't quite distinguish if it's there or not, is a total different issue.
Well, I think that the easiest thing to do is to create the BOM in the drawing, and link the BOM to the right view rather then the front view. Then inside the front view's properties, use the BOM you created from the right view.
