Today after Db resorted form Production / live server, Full CIL failed, And During compilation I found very strange error.
Error described that ” Code Permission Error” And It pointed to out of box SSRS report.
Interestingly a junior developer added customization on report. And there is no error on report.
Finally I found that that report has some out of the box Design for different country localization. Junior developer add customization and delete rest of Designs. So solution is restored the original. Report again deployed, Compiled and error resolved.
