When enabled, Prism accumulates spread discounts. When disabled, spreading a discount more than once replaces the existing spread discount. For example, you can enter one transaction and spread it, then enter a second transaction discount and spread it with the discounts accumulating. Note: This preference does not work on line-item discounts.

Whenever a discount is entered on a transaction, the Prism web client checks the Employee Max Disc % defined in the current logged-in user's employee record to see if the discount exceeds the allowed maximum. If the discount exceeds the allowed maximum, the discount is reduced, with the user informed via a toast message.
If more flexibility is required, users can enable the "Enable Employee Maximum Discount Override" preference. If the "Enable Employee Maximum Discount Override" preference is enabled, managers or other users can override the Employee Max Discount setting.
When the "Enable Employee Maximum Discount Override" preference is enabled and a discount that exceeds the employee max discount percentage is entered , Prism will display an override prompt before reducing the discount.  The prompt has the following options:
Apply Maximum: Apply the maximum amount allowed, reducing the discount if necessary.
Override Discount: When a user clicks "Override Discount," a prompt is displayed for a manager or other override user to log in. This Prompt for Override, Override user sets new maximum for specific discount. The discount amount is entered in the OVERRIDE_MAX_DISC_PERC field in the DOCUMENT_ITEM table.
Cancel: Cancel discount request.
Default=disabled

Disabled (default): If a price change results in a negative discount percentage, the discount percentage is displayed as negative.
Enabled: If a price change results in a negative discount percentage, the discount percentage is displayed as zero; however, the discount amount is still displayed as a negative number. For example, if the Original price was 10.00, and the new price is 11.00, the discount amount will display -1 and the discount percentage will display zero. Promotions that cause a Discount % to be negative also respect this preference (display of Discount % as always positive or zero if preference is enabled).
