Inserting the same project under two sub tasks

[MorganH]

I am trying to set up a master timeline that will show the scheduling of
machine building. The master timeline will be orgainized by the final
product machine being the main tasks, with its sub machines under it. The
problem I am running into are having the need to put the same sub machine
under more then one final product machine. A small sample of the problem is
below:

Machine 1
Sub Machine A
Sub Machine B
Sub Machine C

Machine 2
Sub Machine C
Sub Machine D
Sub Machine E

Both machine 1 and 2 are for the same program, and both have a feeder
machine C. I only need to build one Machine C to feed both main machines.
So as said I want to be able to insert the sub machine into both main
machines, then both main machines into the same master file, when I do so, I
get an error about inserting Sub Machine C in twice (which technically I am).
This master file is not for scheduling, it is to show the total prorgress of
the program, broken down this way to show each main machine and ALL its sub
machines. Any help would be appreciated.

Could you make MachineC a stand alone project at the same level as Machine1 &
Machine2? Then, you would have a milestone in Machine1 and Machine2 that
says "Machine C Available" This milestone would be FS to the last item in
the Machine C build.

I question your WBS if you are trying to insert MachineC twice when in
reality Machine 1 and Machine 2 both share the single MachineC. If there are
physically two machine Cs then you could establish two files: MachineC1 and
MachineC2.

What we do here is establish a MachineC file, and at the bottom of the file
is "Deliver MachineC1, Deliver MachineC2, Deliver MachineC3" as line items
coming from the build process elsewhere within the MachineC file. We link to
the deliveries.
