Promotions at POS

Automatically Apply Promotions at POS
The "Automatically Apply Promotions" and "Manually Apply Promotions" radio buttons in preferences (Admin Console > Node Preferences > Transactions > Promotions) determine whether promotions will be applied automatically or manually. By default, promotions area applied automatically.
If preferences are set to apply promotions automatically, then no user action is necessary to apply promotions at POS. When the necessary items and quantities are entered or when the required subtotal is met, the promotion will be applied. 
You can then view the applied discount in either Item Details > Discounts or Transaction Details Discounts.
Manually Apply Promotions at POS
When preferences are configured to apply promotions manually, the workflow varies slightly depending on the setting of the Tender Action sub-preference (Node Preferences > Transactions > Promotions: Apply Promotions Manually). The available settings for the Tender Action are None, Apply, or Prompt.
None: By default, the Tender Action drop-down is set to None. This means that to apply promotions manually, the user must click the Options button on the transaction form and select "Apply Promotions." 
Apply: If the Tender Action drop-down is set to "Apply," then users can bypass the Options button and instead go directly to tendering the transaction. List the items and quantities that validate the promotion and then click Tender Transaction. A confirmation is displayed to inform you promotions were applied. 
Prompt: If the Tender Action drop-down is set to "Prompt," clicking the Tender Transaction button displays a prompt, giving you the option of applying or not applying promotions.

Item Max Disc % with Promotions
Each item's Max Disc % determines the maximum discount percentage that can be applied to an item. By default, new items have a Max Disc % of 100.  If a promotion calls for a discount greater than an item's Max Disc %, the discount amount for the promotion will be adjusted to the Max Disc %. Note: Promotions DO override the Cust Max Disc % and Employee Max Disc %.
Example 1
Item A has a Max Item Disc % of 10%. Customer Regular Joe has a customer Disc % of 15%. A promotion applies a 20% discount. Result: The Max Item Disc % is enforced, and the discount % is set at 10%.
Example 2
Employee Molly has a Max Empl Disc of 30%. A promotion applies a 40% discount.  Result: The promotion overrides the Max Empl Disc % and the discount is set at 40%.
