If this setting is checked, the simulation takes the percentage value of the probability code that is set for each code into consideration. This means that the quantity of a quote will here be reduced by that percentage value. For example, if the quantity on a quote is 10 and the probability set on the quote is 50%, then the quantity will here be set to 5.
The percentage value for probability is shown using two decimals in the Probability column at the far right of the table. In order to update the table, click on Display List in the window functions, after you have selected or deselected this setting.
In the Help Function for the Probability Codes procedure in the Global Settings module, you can read about how probability codes on quotes can be applied during requirement planning.
