PS Scheduling with subnetworks (PM orders)

Hello all,

I am currently working on a project where I am helping a client use Project systems to manange a plant shutdown. The requiment is to schedule the many maintanance orders (300 +) using project systems to see the critical path and the to manage capacity of the work centers to fit into the time box for the shutdown. I have set up a project down to the network activity level representing the high level process and have started linking PM orders through the additional data b tab, but I have a couple questions.

1.) When you create the link on the additional data B tab. You get a pop up box that will automaticly derive the Project definition and WBS element. Should you link it to all through or should you only select one of the PS objects. What purpose does it serve to show all three or just one PS object?

2.) In terms of scheduling when i attach a PM order to a network and activity it will adapt the basic date of the network activity, however it does not change the day of the network activity to be the same period of the orders attached. I am using buttom up scheduling on the network. Example. I have a network activity with a basic date and duration of 1 day. If I attach a PM order which would require 3 days to complete the network still shows only 1 day. When I reschedule the project should it change the dates on the parent objects? i can see the changed dates when I run a CN41 structure report, but if I look in planning board without the PM orders I don't see the true duration.

Any help would be appreciated on this subject. I am not a PM person. Not sure if this is an issue with a control key.

    hope you have done the OPTP settings. After maintaining OPTP settings then you can link PM order with network activity, which will allow you to do scheduling from Project. Please use CN24N for scheduling.

    Hello,

    I think Abdul has answered your second question. As far as your first question goes, kindly note that the three fields in the Additional data tab serve a specific purpose:

    1) Project definition field is used only for reporting and is something that you will not change.

    2) The WBS field is derived from the network activity to which the PM order is being linked. Please note that this field is used to determine the special stock requirement i.e. the WBS from which the PM order will request reservation of goods provided the special stock indicator is used (this WBS can be changed for example a situation where you have done all procurement of the project on a central WBS as project stock and would like to re-direct all PM order reservations to this single WBS).

    3) The Network is used to link the actual PM order and is used to help schedule it in case the network dates change.

    Hope this clarifies.

    Regards,

    I would also suggest you to use ADPMPS transaction for linking the network activities to PM orders (assigning PM orders as subnetworks to network activities).
