Is there a way to get a list of all outstanding defects for a specific version of CA PPM?
The best way to go about this is to look at the release notes for the next versions of the product after the one you are looking at specifically. For example, if you are looking for the outstanding defects for CA PPM 15.4 (GA), then you would look at the "defects fixed in 22.214.171.124" page for a list of defects that exist in 15.4, but are fixed in 126.96.36.199. Then look at the same for 15.4.1. Those two lists would provide you with the defects that would exist in 15.4 GA, but are fixed in a later version of the product. Unfortunately there is no direct way of getting a complete list of all outstanding defects that exist in a specific version of the product.
