Help Required - How to actualise several activities at once

Morning all,

I wonder if somenoe can tell me a quick way to actualise several activities at once in P6?

I am working on a programme that has several structures within it each with their own WBS section, however a couple of the structures have been removed from our workbank until more funding comes along. So not wanting to remove them entirely I want to actualise all activities in those WBS sections only at the date we were told to defer the work.

Any ideas please?

Thanks

Thom
