You can restrict promotions so that they can only be used at specific locations, or on specific websites.
To set location-based promotion eligibility, you must first enable the Locations feature. See Enabling Other Features that Impact Promotions.
Location and website restrictions are defined on the Sales Channel subtab on the promotion record. For more information, see Setting Sales Channel Eligibility on SuitePromotions.
There are limits to the number of promotions that can be automatically applied based on schedule and location. For more information, see Auto-Apply Promotions Limits.
