A LOE activity is similar to a Hammock but the text below is from my Primavera Enterprise book and explains the difference, I hope this is of assistance:
The LOE Activity Type spans other Activities. Therefore the Start Date, Finish Date and Durations may change as the start or finish date of activities that it is dependent on change during scheduling or updating. LOE Activity Type is similar to a Hammock in P3 and SureTrak, but more relationships may control the Start and Finish Dates. There is no equivalent in Microsoft Project. This type of activity does not create a critical path irrespective of the float calculations that are displayed.
The Start Date is controlled by the following relationships:
- Finish-to-Start predecessors
- Start-to-Start predecessors (this is the only relationship that controls a hammock)
- Start-to-Finish successors
- Start-to-Start Successors
The Finish Date is controlled by the following relationships:
- Finish-to-Finish predecessors (this is the only relationship that controls a hammock)
- Start-to-Finish predecessors
- Finish-to-Start successors
- Finish-to-Finish successors
Resources assigned to a Level of Effort activity are not considered in calculations when a schedule is Leveled.
Level of Effort activities may not be assigned a Constraint.
