Hi – I am using Project 2010. I created a file with master and subjects, made duplicates (two copies), deleted unnecessary tasks in these two copies, inserted these two subjects (copies) as a sub project – see http://i.imgur.com/uuhoykf.png. I changed the bar style of project summary tasks and the bars – see http://i.imgur.com/H9gLmif.png. It works perfectly fine by applying the new style for inserted project’s project summary task and its tasks – see http://i.imgur.com/EQdn8e6.png. If you can share the files to sai.prasad.b[at]gmail.com, I can try to help you out.
