Item Unit Flag
Check this box if this cost type on this phase will be used to accumulate units complete for the related contract item. When summarizing job costs, the costs are all totaled, but only the units posted to the specified phase/cost type are counted. This option is typically checked for only one cost type on one phase linked to a contract item, and the phase selected would be the one most closely related to the contract item.
Leave this box unchecked if this cost type will not be used to accumulate units complete for the related contract item.
