Same month last year
You can use the same month last year as the historical period in the calculation of seasonally adjusted accruals for both cost and consumption values.
The method uses the same month last year relative to data gaps to calculate accruals.
Note: If an
account has not captured data for the same month last year, no accruals are generated. This might
occur for an event type of data, such as stationary fuel.
Table 1 presents some examples of how this
algorithm uses the same month last year in calculations.
| Month with gap | Accrual calculation |
|---|---|
| December 2023 |
Daily average value for December 2022* Number of missing days
in December 2023 |
| September 2023 |
Daily average value for September 2022* Number of missing days in September 2023 |
