The tab holds the data of one reference date rule. The fields are listed in the order they appear on the screen.

• {Category} — FMCG category the rule applies to. The first option in the list is All other — the rule for products and services without a category; it is followed by the categories Food, Cosmetics, Beverages, Household products, Cleaning products and Toiletries. These are the same categories assigned to items with the {FMCG category} field in the ~ BASIC ~ and Item Groups tabs.
• {Valid from} — Date from which the rule applies, as a rule the day the regulation takes effect. From that day Brix uses this reference date for items of that category instead of the one from the older rule.
• {Reference date} — Day whose price is displayed as the base price (“Price on”). Cannot be later than {Valid from}.
  • If the item had no price yet on the reference date, the base price carries the date of the item's first appearance in the price list instead of the reference date from the rule.
• {Regulation} — Designation of the regulation the rule comes from, e.g. NN 75/25; at most 40 characters.
• {Description} — Free one-line explanation, e.g. which decision kept or repealed the rule. Optional.
