Dedicated scheduling of a planned order having a fixed activity

Question

Hi Gurus,
We're using PP/DS Optimizer with Total Delay Costs objective function, following a Backwards Scheduling strategy in order to Reduce Premature Scheduling. Order activities are then scheduled as close as possible from the requirement dates. However we would wish to apply a forward scheduling strategy to the orders having a fixed activity, but starting from the existing order planned start date instead from the system date, i.e:
Requirement X due on 18.01.2012
Output firmed planned order Y with 3 activities (A1, A2, A3), A2 beeing fixed
Optimization result with a Backward scheduling strategy:
A1 09.11.2011
A2 18.11.2011
A3 17.01.2012
Optimization result when Backward scheduling setting is unchecked
A1 NOW
A2 18.11.2011
A3 17.01.2012
The business requirement we d'like to achieve
A1 09.11.2011
A2 18.11.2011
A3 19.12.2011
It is not foreseen to fix A1 to bypass the problem, above example is only a basic example whereas there're multiple activities in between A1 & A2 in our real material PDS. Is there any way (even with another optimization run, or using in combination a Production Planning Run...) to achieve such a scheduling strategy?
BR,
Pascal.

Hi,
To add further and to more precise, the issue is:
In CM01[or in any capacity evaluation tcode], In a particular maonths load[Period] the opeartion from different month is showing up.
For example: if Period[month] 06 is veiwed of a Workcenter load, a line[load appears], whose earliest date is in 7th month[01.07.2014].
I expected to see, only Workcenters scheduled in 6th month to show up in the load evaluation.
Please look at the screen shot.
