Sales Price generated per dimension

I would like to know if it is possible to have Sales Order Price per dimension automatically generated like the cost. I have created an item, specify a dimension group for Configuration only. In Price update section, I have selected : Sales Price Model : Contribution ratio Base price : Cost Price Contribution : 20.00 For purchasing, I have created Trade agreement : Purchase prices for each configuration. When doing purchase order and receiving it, I do have an entry per configuration with the proper cost in ‚ÄúCombinations of item dimensions‚ÄĚ table. BUT when I try to issue a sales order, no selling price is generated??? I am expecting to get a price of actual cost of this dimension plus 20% markup. Any idea? Anybody have tried to do this with successful result?[?] thanks Danny
