Creating a resource in ms project

Question

Hi,
We are a Construction company and recently we started using MS project.
We have created three resources cement, sand and aggregates.
Now we want to create a fourth resource named RCC whose unit is CMT which uses cement, sand and aggregates in following weightage;
1.  8 bags of cement
2.  0.9 of aggrgates
3.  0.5 of sand
So if we take cost of cement as 100 dollar per unit and aggregate 15 dollar per unit and sand 5 dollar per unit then the cost of RCC per CMT will be as follow;
100 * 8 + 15 * 0.9 + 5 * 0.5 = 816
Please send us a template if possible.
Thank you.

Hi Piyush_0,
May I ask what is the reason behind having the fourth resource? Is it for cost purposes or for allocation/assignment (when assigning on CMT you will need 8 cement etc.)
If it is the first option, then you can try to use the standard rate and/or cost per use
If it is the second option then you will need a VBA macro (e.g. after assigning the CMT run the macro so the corresponding cement, sand, aggregates are assigned to the task as well)
