MS Project uses Work and Duration. OmniPlan uses Effort and Duration. When creating a schedule in MSP, you set the Duration and the Work field stays at 0 until you assign resources. If the schedule is imported into OP, it appears that MSP's Duration field is copied over to both OP's Duration and Effort fields. Upon export to xml, the Effort field is copied to the MSP's Work field. MSP thinks that resources are assigned and this causes problems.

I purchased OP based solely on its advertised ability to work with MS Project. I have spent over a week trying to figure out how to successfully use OmniPlan with MS Project on a real project and have gotten nowhere.

Have you guys actually tried using OmniPlan with MS Project?
