Re: Can a defect be shared by 2 Diff Projects in QC
You're correct that there is no way to share a defect between to projects. If you replicate the data, then you have two defects to keep updated as the status changes. You can write some fancy workflow code to keep defects in sync between projects, but it's a big pain.
To copy, just open two browsers. Login into Project1 on one browser and then Project2 in the other. Copy the defect from Project1 and paste it in Project2.
