| # Resetting authorizations Over time, the FAB authorizations and RAW authorizations can be incremented to very high values. To decrease these values, when resetting the CUMs in the Reset Cumulatives (tdpur3230m000) and Reset Cumulatives by Contract Total Line (tdpur3230m100) sessions, the FAB/RAW authorizations are also reset. Similar to the cumulatives, authorizations cannot be reset exactly when the year is changing. As a result, updates can be stored in the FAB/RAW Authorizations (tdpur3534m000) session 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): Order based CUM model Receipt based CUM model Conditions for successfully resetting the FAB/RAW authorizations Suppliers and customers must use the same CUM reset date when resetting the cumulatives in the Reset Cumulatives (tdpur3230m000), Reset Cumulatives by Contract Total Line (tdpur3230m100), and Reset Cumulatives (tdsls3230m000) sessions. Resetting can only take place when the releases sent by the customer, are received and approved by the supplier. If not, suppliers cannot approve releases that are processed after the reset date, because the reset dates are different. Purchase release lines with the status Created, or Scheduled are automatically reset. Suppliers must not update incoming releases or manually create new releases, because resetting can then result in wrong quantities. To calculate the reset quantity To reset the existing FAB/RAW authorization values, the reset quantity is determined and subtracted from the existing FAB/RAW authorization values. Based on the CUM model, the reset quantity is calculated as follows: Order Based CUM model Reset Quantity = last required quantity that is communicated on a release date that is prior to the new reset date. This quantity is retrieved from the Required CUM field of the FAB/RAW Authorizations (tdpur3534m000) session. Receipt Based CUM model Reset Quantity = last received quantity that is communicated on a release date that is prior to the new reset date. This quantity is retrieved from the Received CUM field of the FAB/RAW Authorizations (tdpur3534m000) session. To reset high FAB authorizations/high RAW authorizations How the high FAB authorizations and high RAW authorizations are reset is based on the setting of the Authorizations to be parameter in the Purchase Contract Line Logistic Data (tdpur3102m000) session and/or the Items - Purchase Business Partner (tdipu0110m000) session: Carried Forward The high FAB authorizations and high RAW authorizations are reduced by the reset quantity. Reset The high FAB authorizations and high RAW authorizations are equalized to the FAB authorization and RAW authorization values. Example FAB period = 4 weeks. Cumulative model = Order Based. Reset date = start week 3. The schedule lines are generated before the reset takes place. Schedule line 2 is released in week 3. Schedule line 3 is released in week 5.
Authorizations to be Carried Forward

- | Qty. | CUM | Qty. | CUM | Qty. | CUM | -

2 | 20 | 40 | - | 40 | - | 40 | 40

TOTALS | CUM Line 1 | CUM line 2 | CUM line 3 | CUMs after reset
--- | --- | --- | --- | ---
Start CUM | 0 | 40 | 50 | 10
FAB | 80 | 110 | 85 | 45
High FAB | 80 | 110 | 110 | 70
The reset date starts in week 3. Because of the Order Based CUM model, resetting is performed based on the required cumulatives. At the end of week 2, the reset quantity is 40. When Authorizations must be Carried Forward, the authorization cumulatives are updated by -40 from the reset date on (week 3). If you take the same example, however, with the authorizations reset rather than carried forward, the high FAB is not updated but equalized to the FAB quantity. The calculation then arrives at:
TOTALS | CUM Line 1 | CUM line 2 | CUM line 3 | CUMs after reset
--- | --- | --- | --- | ---
Start CUM | 0 | 40 | 50 | 10
FAB | 80 | 110 | 85 | 45
High FAB | 80 | 110 | 110 | 45
Note (High) FAB and (high) RAW are only recalculated for records that belong to material releases, not shipping schedules. In the Purchase Release (tdpur3121m000) session, FAB and RAW related fields of purchase release lines with the status Created or Scheduled, are also reset.
