In our lab we use OpenLab CDS 2.1 and have a specific Group set up for our analysts and a separate Group for reviewers. When we create a new project, we set the signature levels so that the reviewer Group is Level 2 and the analysts are Level 1. Both user types are given the same Role, with the ability to lock/unlock result data sets enabled. When it comes to e-signing and locking data, a reviewer can do both with the higher privilege level, but then any analysts could unlock the data set even though they have a lower privilege level. Is there a way in Openlab to stop this from happening, i.e. when a data set is locked by a Level 2 user, it could only be unlocked by another Level 2 user? Or would the only alternative be to create separate Roles for Level 1/2 with the ability to unlock data only enabled for Level 2 users?
