You should have it already, if you get the updates - it just has an RTX extension instead of RTM.
 
Make a copy of your current RTM (if you've done any modification), an then rename the RTX to an RTM.

Those appear to be the latest versions.
 
You should be able to add them using Report Editor.
 
Click "Add DBBarCode", double-click in the empty white box immediately to the right of Data > DataField in the left-hand pane, find the table you want and select the field.
 
Note that the table you will want to select will depend on whether you want the Parent Part Number or Component Part Number. I would expect you'd want the Component, which you should be able to find in WOBOM > WOMOM.COMPCODE. Quantity would probably be WOBOM.TOTQTY.
 
You may have to do some experimenting....
