Notifications (Bell) only when Purchase Order value is within approval range (Minimum–Maximum)

Hello everyone,

I have a question regarding approval notifications in IFS.

Context:
When newly created or planned purchase orders are released for approval, only the relevant approvers should receive a notification (bell icon) if the purchase order value is within the defined approval range (Minimum–Maximum) of the approval rule.

We have already maintained the Minimum and Maximum values in the approval rule (see screenshot).
However, it seems that notifications are still being triggered regardless of whether the order value is inside or outside this range.

Requirement:
Notifications should only be sent to the assigned approvers when the purchase order amount falls within the defined Minimum and Maximum range of the approval rule.

Questions:

1. Is it possible in IFS to trigger approval notifications only when the PO value is within the defined amount range?

2. Is additional configuration required (workflow, event action, or routing setup)?

3. Or is this standard behavior and cannot be restricted by amount range?

Any guidance or best practice would be highly appreciated.

Thank you in advance!
