Resetting purchase schedule cumulativesOver time, a purchase schedule's cumulatives (CUMS) can be incremented to very high values. To decrease these values, you can reset the CUMs in the Reset Cumulatives (tdpur3230m000) and Reset Cumulatives by Contract Total Line (tdpur3230m100) sessions. Although this reset is usually performed at the end of the year, the CUMs cannot be reset exactly when the year is changing. This means that updates can be stored in the cumulative sessions after the reset date. By calculating a reset quantity, these values are also included in the reset process. Resetting is carried out based on the following cumulative (CUM) models, which you can define in the Model for CUMs field of the Purchase Contract Parameters (tdpur0100m300):
Conditions for successfully resetting the
cumulatives:
To calculate the reset quantity To reset the existing CUM values, the reset quantity is determined and subtracted from the existing CUMs. In the Shipped Cumulatives (tdpur3131m000), Received Cumulatives (tdpur3132m000), Required Cumulatives (tdpur3130m000), and the Invoiced Cumulatives (tdpur3133m000) sessions, a reset record is added and the CUMs are reduced by the reset quantity. Furthermore, the FAB/RAW Authorizations (tdpur3534m000) session is reset and the release lines that are generated, but not yet sent, are reset. Based on the CUM model, the reset quantity is calculated as follows:
Example 1 - Order Based CUM model
The reset date starts in week 3. Because of the Order Based CUM model, resetting is carried out based on the required cumulatives. At the end of week 2, the reset quantity is 40. As a result, all CUMs are updated by -40 from the CUM reset date (week 3) on. Example 2 - Receipt Based CUM model Take the same data from the previous example, but also take into consideration the following data:
The reset date starts in week 3. Because of the Receipt Based CUM model, resetting is done based on the received cumulatives. At the end of week 2, the reset quantity is 35. As a result, all CUMs are updated by -35 from the CUM reset date (week 3) on. The totals from example 1 would then arrive at:
