In the order recommendation list it is possible to determine the quantity to be ordered automatically, even if the last possible date has not yet been reached. Select the number of buffer days, as well as the desired procurement method. Then, the test starts determining what quantity should be ordered, taking into account the lead time + buffer days (working days):
PATH: MRP > MRP Wizard/Order recommendations > Select a scenario > Order recommendation button > mode button > Pre-assign button.

Calculation
The requirement date (list of peggings) is less or equal to the current date + lead time + buffer days given in working days. The sum of the affected peggings, taking into account the already planned receipts in this period, is the quantity to be ordered or to be produced. The calculated delivery date is, at earliest, the current day (today) + replenishment lead time + buffer days (work days). The determined date is at least one day after current date + replenishment lead time. If the determined day is not a working day, the next working day is identified and proposed. The determined values are entered in the order recommendation item list (upper part) in columns "quantity" and "requirement date". Click the Purchase Request or Production button to complete the process.
Note: This pre-allocation function considers only storage-related assemblies.
Attention: Supplier and price need to be entered prior to the creation of purchase documents. Items without this information are ignored.
Examples for the calculation of the order proposed date with help of the pre-allocation function:
| 1. | Lead time from the item master appears in the calculation is 20 days. |
PATH: MRP > MRP Wizard > Select a scenario and click the Order recommendation button
Window: mrp_view_masterrahmen
| 2. | Fill PO quantities. Additional days can be entered. |
Period = Current day + Lead time (item master) + work days
End of the period = 24.07.2010
The last requirement of 31 pieces from 26.07.2010 is outside the period.
Period = Current day + Lead time (item master) + work days
End of the period = 23.08.2010
The last requirement of 31 pieces from 26.07.2010 is now inside the period.
