Lost Work Items
If a Start Point feeds directly into an object that has limited capacity, so an Activity or a Queue with a set capacity, then there might not be space for a Work Item to be able to wait until it can be processed. In this case the Work Item is said to be lost.
A warning message is generated each time a Work Item is lost. To not show this error message then check the box “ignore hints about lost work items” in your Start Point.
