Price Lists

Hi,

I am trying to set up Price Lists (Oracle Pricng Manager)  in the following manner but am unsure how to go about it

I have a number of items in the same product category. One would be deemed to be the base product whereas the others would be consistently the same differential off the base price

So I was thinking that i would set up the base item as the product category as such with the other items feeding off this base price.

Every time the base price changed, all the other prices would automatically follow suit by their differential from the base price. The price list could be maintained by one person
