Resource unit of measure

Is any way to material resource as primary resource - thats depends on if the # Units of the material is driving the activity

Second how to assign of unit of measure such as hour for labor and non--labor - yes go to the resource and look under the  

details tab and there is a drop down there for unit of measure. If you do not see the one you want you can add it by going to Admin then Admin Categories then Units of measure 

Third in resource tab of activity details of update primary resource is any setting to automatically update other resource

go to Projects and on the Resources tab under Resource Assignments set the settings there

Agree, when consumable resources such as raw materials are lacking activities are delayed.
