U/M
Enter the standard unit of measure in which this cost type for this phase will be tracked. Must be a valid unit of measure set up in HQ Units of Measure.
For labor, the unit of measure should not be HRS (hours) in most circumstances. Units are separate from hours, and actual units will not be updated with hours from Payroll. The UM should be the quantity to be completed. If no quantity (units) is being tracked, it may be set up as LS (lump sum).
