• All data sources need to have a coherent data periodicity, meaning that the values need to be observed and registered in the same interval. 
• If you are collecting your sales numbers on a weekly basis, the sales need to have exactly one observation per week, country, region, product, and grouping.
• The Date provided should always fall on the first date in the period. In the example below, we want to register the total sales that happened in ISO Week 32, which starts with Monday, August 8, 2022, and ends with Sunday, August 14, 2022. Thus, the sales are put on the first day even if all sales have not been realized that specific day. This is okay since the date will refer to the entire period of Week 32. The first day of the week is shown in the calendar below.

Note

Even if you live in a country where your calendar week starts with Sunday, Alvíss AI follows the ISO date standard, where each week starts with Monday.
