SAP B1 Price List Calc Query

SAP Business One 9.3 PL0

Price List query

Instead of using the 'factor' on a price list to multiple to get the selling price.

Is it possible to setup SAP B1 to divide to get the selling price automatically calculated.

eg 8.05 / .90 = 8.95 (rounded)

instead of using the current 8.05 * 1.11180 = 8.95 (rounded)

Thanks, Eoin
