Problem with export to Microsoft Project
 

I have exported an Omniplan file to MS Project (using the XML option) and imported it into Project 2007. It displays fine, and the columns show the correct dependencies. However, when my client moves a task to the right, an error message is shown to say that the action will cause a scheduling conflict, whereas, based on the settings, dependent tasks should move to the right - as they do in the Omniplan file.

A couple of hours investigation has shown that none of the tasks exported from Omniplan behave properly in MS Project - changing constraint type has no effect, and they do not move around via dependencies.

I have compared all the settings for a new task entered in Project, that behaves normally, with ones imported from OmniPlan and can see no differences. To rule out a problem with my file, I created a new one with only three dependent tasks; exactly the same problems occurred. I have also tested on two different Macs (Omniplan) and PCs (MS Project), and tried both the Project XML and MPX export options.

I detest Project as much as everyone else, and love Omniplan, but my client uses it and insists on receiving files in Project. Any help will be gratefully received. The Omniplan, XML and MS Project files are attached for the three task test in case that is helpful.

I am having exactly the same problem. It seems that all dates are held as fixed dates. There also seems to way to simply change this is MS Project. Is there anyway to change this in the export?

You really ought to contact the OmniPlan support ninjas via Help->Send Feedback (which will allow you to attach a copy of your project file with the sensitive information obscured). That's the only way to make sure that someone who knows the ins and outs of the program sees it in a timely fashion. I don't have any MP experience, nor a copy of it to play with, so I can't really offer any suggestions.

If you have dragged things around on the OmniPlan Gantt chart, that schedules specific start dates for those tasks rather than letting them fall where the constraints would otherwise allow. If you select all the tasks in your project and click the Reset button in the Task Information inspector to set them all to be scheduled as early as constraints allow, then export to MP, does the resulting document work properly (ignoring any issues about how some things aren't starting at the right time because you didn't have fixed dates for them in OP)? Not proposing this as a solution, just a way to get a start on isolating the problem, of course...
