Here are the columns I used when importing a large batch of tasks into a specific project: Start Date: setPlannedStartDate (we used a task constraint of Fixed Dates, so the start date was in conjunction with setPlannedCompletionDate) Duration: We have setDurationType as A and setDurationUnit as D too, but I think you will also need both setPlannedDuration AND setPlannedDurationMinutes (in minutes). These two fields also exist as setDuration and setDurationMinutes, not sure how these are different. Planned Hours: setWork for the hours, AND setWorkUnit = H for hours Hope this helps! abcdabcdabcdabcdabcdabcd Alison Wells, MBA Senior Business Analyst Corporate Information Systems Business Systems Group Community Administrative Support Building (CASB) 2530 Divisadero St, Fresno, CA 93721 Office: (559) 459-7008, Internal: x57008 Cell/Pager: (559) 287-6800 - WARNING/CONFIDENTIAL: - This email, including attachments, may contain information that is privileged, confidential, and/or exempt from disclosure under applicable law (including, but not limited to, protected health information).
