+A semi-additive measure, also known as snapshot data, is a measure that is usually aggregated for all attributes except for date and time. For certain measures, like inventory, you want to know what the value was at the beginning or end of a period. In that case, you can use the `last_value` function to find the inventory at the end of a month, rather than aggregating all values over the month. Similarly, you can use the `first_value` function to find out your stock at the beginning of a month. To enable this feature, contact your administrator.
