Hi all,
We met one issue that every time updating the quantity for a Schedule work item details (one sub item),
the cost rate is updated also. But we didn’t get the relationship or calculation rule.
Any advice is appreciated.
Question
Cost rate is changed

+3Hi
When you update project estimates from the Schedule of Work, the system recalculates activity-level estimates and applies them to your project. This is done using the Update Project Estimate command on the Schedule of Work Value Summary page.
Key Points:
- Prerequisites:
- Estimates must be calculated using the Calculate Value function.
- The Schedule of Work Estimate must be in Approved status.
- System Effect:
- Activity estimates are updated based on calculated values in the Schedule of Work.
- All item lines must be connected to a cost or revenue element.
- Updated estimates can be viewed in:
- Project Estimate Update Overview
- Project Estimate Update Detail
- Project Monitoring

Why does the cost rate change when quantity changes?
In IFS, cost rates often depend on:
- Calculation rules defined in the Schedule of Work (e.g., cost per unit).
- Resource or labor cost elements linked to the work item.
- If the cost element uses a unit-based calculation, changing quantity will proportionally affect the cost rate.
