Workfront does not have a data field for planned labor cost for the assignment object. Workfront users do have access to an assignment's logged hours via the actualWorkCompleted field, though users cannot chart this field as it can only be accessed through Syntax mode.
I can calculate the planned labor cost of an assignment with the following syntax text mode code:
aggregator.displayformat=currencyStringCurrencyRounded
aggregator.function=SUM
aggregator.valueexpression=PROD(DIV({workRequired}/60),{role}.{costPerHour})
displayname=Planned Cost per Assignment
textmode=true
valueexpression=PROD(DIV({workRequired}/60),{role}.{costPerHour})
valueformat=currencyStringCurrencyRounded
Having this as a native field in Workfront would allow us to chart the data.
