Thank you Malcolm! AFAIK I can only define one SystemSetManager and fill it up with all clients. Because of SLA's with our customers we defined for each system a special Maintainance Window. Some Servers have to be patched on every first Monday at 6pm, some servers only on third wednesday 9pm ... and so on. In the past with another Tool (I won't say the name ;-) ) we defined the MW only once and the patching for the system runs without any handling.

For this I think that we need multiple SystemSets? Is this paossible through Web-GUI?
