This request has been asked previously by other customers too and our product teams have discussed on this feature. The end result is always that we can only use hourly rate, because all our Timesheets are in hours or fraction of hour. Because of workloads, vacation accrual and pay structure, it’s really tough to create a “universal solution” to get hourly rate from a salary (weekly or monthly). Hence, this is a product limit for the moment. Please feel free to vote on the following idea:
