Novell ZENworks Configuration Management 11.2
Enforce policies immediately can be set only for policy assignments on devices not exceeding 30.
Distribution Schedule can be set to "Now" only for bundle assignments to devices not exceeding 30.
ZCC restricts the number of schedule "Now" for bundle distribution or policy enforcement to 30. This is by design to avoid performance problems on primary servers. Each "Now" schedule is handled by a quick task, and excessive quick tasks can cause server performance problems.
