I am currently on version 5.0.2 of DOORS NG and I have three levels of requirements in modules all requirement artifacts are linked together like this: top level requirements module linked to mid-level derived module requirements linked to low-level derived module requirements using the out of the box link Decomposition (Parent of / Child of) link type.  I can follow the traceability links using the links explorer.  What I would like to be able do is be in the lowest level module and see the traceability parent of and child of columns back to the top level requirements but I can only see to the mid-level requirements.  Is there a way to see from the bottom up to the top level module using traceability views?  I would like to use the views to easily produce a traceability matrix for customer review.  Any help would be greatly appreciated.
