Procurement measured in cost sounds odd, would all depend on the project though.

You can use performance % complete which is the activity % complete  based on the Percent Complete type.

depending on P6 version your using, below P6v17xx or P6v16xx Performance % Complete - labour units is not available and only cost driven so I recommend to micmic the budget hours by setting $1 = 1 hour for Engineering and Costruction so you can have Overall % complete per WBS and overall using Performance % complete.
