In earlier release if you select the Each Combination of Items Above radio button, in the Pricing Rule Summary screen for all the combination pricing rules there was no explicit text box to enter the discountable quantity per combination. However, in release 9.3, a new text box called Discountable Quantity per Combination* is added when you select either Same/Low Priced Item for each of the combination or the Each Combination of Items Above option. Checking this radio button enables the user to enter the discountable quantity per combination which is defaulted to 1. Hence, if you have migrated from previous release, and if you have selected the Each Combination of Items Above radio button in the previous release, then, by default the value of the Discountable Quantity per Combination* text box is set to 1.
