Vladimir,
I need a little help understandin partial workload and skills.
As far as I know (and tried) you cannot assign partial workload at the skill level, only at the resource level in the skill. when doing so Spider doesn't apply the partial workload if the skills have 100 workload, even though the resources inside the skill are set for partial workload.
However, if you assign the value of the minimal workload to the skill workload then Spider applies the partial workload to the rest of the activities.
Here are pictures:
1. Both activities with skills have 100 workload and partial workload to resource:
2. One activity has skill at the minimum workload of the resources and the other is at 100:
Best regards,
Bogdan
My mistake for incomplete description:
Resource A and Resource B will be named resources, say John and Mary.
In order to schedule John and Mary and not 2 John or 2 Mary I used Resource Constrained Scheduling.
Bogdan,
it is possible to assign partial workload to resource skill assignment.
I cannot repeat your example. When I do it Spider Project selects two units of resource A to one activity and two units of resource B to another.
