Every dimension item can be assigned a start date and an end date. These dates are optional and do not affect the calculation of any rebate. These dates control which dimension items are displayed when assigning dimension items to a program line.
For example, take a product with an end date of July 31, 2022. If you created a program line that spanned from January 1, 2022 to December 31, 2022, the aforementioned product would appear for selection within the program line, regardless of its start date.
However, a product with a start date of January 1, 2023 or an end date of December 31, 2021 would not be available for selection within the program line.
