Hello and good afternoon sirs and madams,

I have a specific issue regarding a material resource. It might seem a bit dumb but i just started my Master in Project Management and these days are marking my first encounters in MS Project.

Describing the issue:

We (a friend and i) were assigned to plan a project for a complete maintenance of an Oil Refinery . In some of the tasks i have to assign a material resource ( a crane to be exact) . The Crane's cost is 400e/day . Our problem is this , we are trying to make this dynamic(for task duration changes) . For example . In the 1st summary task the crane is being used for 22 hours , and in the second 13 hours . We want to assign the Material crane resource to calculate the exact cost per days (f.e. if total 1.3 per summary task to calculate the cost of the crane 2x400 ).

I hope you peeps got what i mean, and the help will be very appreciated , because we are really stuck trying to program this with durations on excel and nothing seems to solve the puzzle

Thank you
D
