There are 3 ways that multipliers can be managed within IFE. Depending on where there multiplier is changed will determine the order of precedence that multiplier will have. It is important to understand this order of precedence which can be used to your advantage to change multipliers in one spot and have that change automatically apply to all items in a tender. Unless there are specific reasons to apply a multiplier to a specific option or item all multiplier changes should only be done at the Project Level. If this methodology is used you can change the multiplier in one spot and have it apply to all items.
Multipliers can be managed at the:
Multipliers managed at the "Option Level" take precedence over the Item or Project Level.
Multipliers managed at the "Item Level" will take precedence over the Project Level.
Multipliers managed at the "Project Level" will apply to all Items and Options (except those changed at the Option or Item Level).
