I am finding that I am unable to modify an existing deployment. I wonder if this is a problem with rights or something else. Looking through other posts it appears that the ability to modify deployments has been removed from SCCM - so I think it is normal - just want to confirm.
My situation is this. I have a collection of machines created by direct membership. I deployed a certain package/program to them as "available" At the time the deployment was created, the application owner did not want to set a mandatory time. Now she does. In SCCM 2007, I would just add a mandatory time to the existing advertisement. In 2012 I find that I am unable to add a mandatory time to an existing deployment. "New..." is gray.
Looking at other deployments that have mandatory times, I am able to add and change the mandatory time easily. But where the deployment is shown as "available" I cannot change it to required.
I wonder what is the proper equivalent to adding a mandatory time to an existing deployment.
Do I make another deployment and this time choose a mandatory time? 80% of the target has already run the package - so I must not force them to run it again. If I set it to run only where failed, then will everyone who ran the "available" deployment be spared from having it run again at the mandatory time in the new deployment?
