In Office version 2007, I have some tasks that are all fixed duration. I'm a prime contractor with subcontractors and I'm trying to schedule out events. I have add the duration and assigned the resources, however on some of them I count up the days and they don't add up correctly or one does not start until another ends. Here is an example:
Task ID 4 - Design Approval Start Fri 8/29/29/2014 Finish 9/5/2014 Then I have order equipment with each manufacture having a different lead time for delivery and all the predecessors are on task ID 4. Task 6 Vendor 1 Duration 2 wks Tue 9/9/2014 Finish 9/23/2014 Resource Company A Task 7 Vendor 2 Duration 3 wks Fri 11/14/2012 Finish Wed 12/10/2014 Resource A
See the problem task 7 should start on the same day as Task 6 because the predecessor is the same task ID 4.
All constraints are as soon as possible.
