I posted some info on copying report designs between 2 workflows. However, you should make sure that all necessary fields are sent to the report before attempting to paste in the report file. This approach works better when updating workflow “versions” rather than trying to bring in another BIRT report as a “template” for use in completely different projects.
Thanks for provide reference, but it might be diffcult to beginner ,do you have any example?
I found another way is just copy workflow in workspace, it will works.
