Linking to current costs

Hi Guys,

Looking for a point in the right direction if anyone can help id begrateful.

I have quite a few different products modelled in SW. The productsconsist of a number of different lengths of weldments sectionsassembled together, eg 50x50x3mm square box etc.

The problem is that the price of steel flucuates so much that ineed to keep track of our costs.

Is there way that i can link an external price list of say priceper metre of each steel section which would then feed into all thedifferent products and update the cost?

This would be an amazing help to me if i could get it sorted.
Thanks for any help in advance
