Partial Week Promotion Definition

We’ve enhanced how Promotional Causals can be defined!
Previously, promotions could only be set at the weekly level. With this update, you can now choose “Use Specific Dates” to define promotions using exact start and end dates on the calendar.
What’s New
When a promotion only partially covers a week, you’ll now see this reflected in the week label. For example: W43 (4d)
 → indicating that the promotion runs for 4 days in Week 43.
Both Allocation and Assortment modules will automatically handle these partial weeks.
The discount and lift values for the promotional causal will be proportionally applied to the corresponding week.
This enhancement provides more flexibility in defining promotions that don’t fit neatly into full-week periods — making your forecasting and planning even more accurate.
