Hi John, the issue is, that in Workfront you can't have multiple hour entries on one task/day combination. We solved this by creating hour types "Line 2", "Line 3" and so on. If the user adds hours manually, he just has to select a different "line", if the hours are filled by the API, we first check for an available "line" and us that to add the hour. Hope this helps!
