Show/Hide Data Panel on RAC is grayedout when we access structure manager, How to activate?
Go to Solution.
If the issue is just for a single user or on a single computer
Try to reset the perpsective from Window->Perspective -> Reset Perspective.
If it doesnt work, delete the RAC cache folder from %userprofile%\Teamcenter.
Also, if the issue started after deploying any rich client plugins, try rolling back your changes. Dont forget to run %TC_ROOT%\Portal\registry\genregxml.bat
If none of them worked, it could be because of data in context. So might need more details to undestand the problem.
