A cost rule can be adjusted by changing its currency, rate, or effective date(s).
In version 9.30, the following restrictive measures were implemented to ensure the changes to an existing cost rule has no impact to other projects where their time sheets contain a time period that falls into the duration of this cost rule. This prevents changing existing cost values from unwanted recalculation.
If the effective finish date of an existing cost rate is earlier than the current day (today), the cost rate cannot be modified.
- If the effective finish date of an existing cost rate is later than the current day (today), but the effective start date is earlier than today, you can only adjust the finish date, and the new value for the effective finish date must be later than the current day (today).
- If both effective dates of an existing cost rate are later than the current day (today), all fields of the cost rate (including its currency, rate, and effective dates) are adjustable.
Note: If you do need to modify the currency, rate, or effective date(s) for an existing cost rule, you can still do so by clicking the Modify Existing Rate button on the Edit Cost Rule page. However, always be cautious when you make this decision.
You can also affect all cost rules by reordering the precedence of cost factors. Cost rules can also be deleted.
