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 flag is generally checked for only one cost type on one phase, and the phase selected would be the one most closely related to the contract item.
Leave this box unchecked if you are not using this cost type to accumulate units complete for the related contract item.
This flag is only used in reporting progress posting (JC Progress Entry) and projections (JC Cost Projections).
