In Spectrum, is there a way to hide In Maintenance yes/no selection on the Information tab in the Component Detail section to force users to use a schedule?
I *think* you can do it by taking away the Model Management --> Model Write --> Model Maintenance Mode privilege from the user group.
What I can't remember is whether taking that away also prevents a user from scheduling maintenance mode via the scheduler or not.
A quick test in the lab using Spectrum 09.03.00.H01 shows "Model Maintenance Mode" and "Model Maintenance Mode Schedule" to be two separate privileges. If "Model Maintenance Mode" is unchecked and "Model Maintenance Mode Schedule" is checked, the user can schedule Maintenance Mode but cannot enable/disable Maintenance Mode.
