The rescheduling tolerance refers to a scheduling difference between
- the original target delivery date of a current purchase order and the changed requirement date of this purchase order or
- the target completion date of a current production order and the changed requirements date of this production order,
below which the ERP or scheduling system should not display a rescheduling proposal.
More powerful ERP or scheduling systems inform users by suggesting rescheduling that a current order or production order no longer corresponds to the demand situation and should therefore be brought forward, postponed or canceled. The need for rescheduling always arises when the requirements for purchase orders or production orders have been postponed.
Current orders or production orders can no longer be changed automatically by the system, as they require consultation with the supplier or production. The ERP or scheduling system therefore alerts users to the need for action by suggesting rescheduling.
The number of daily rescheduling proposals can quickly become very large and therefore confusing. In such cases, the rescheduling tolerance makes it possible to ignore postponements to which users cannot react anyway.
Normally, the rescheduling tolerance can be set item-specifically and different values can be defined for tolerances “forwards” and tolerances “backwards”.
Our tip:
Use the rescheduling tolerance for items with long delivery times. Especially in the case of ship freight , a certain delivery date deviation is always to be expected. Rescheduling proposals that are below the usual delivery date fluctuation can be avoided directly by means of a suitably set rescheduling tolerance.
Even for items with very short production lead times, unnecessary rescheduling proposals can be avoided by means of rescheduling tolerance. If production orders are running for these items, it usually makes little sense to slow them down again and there are few opportunities to speed them up further.
