Hi Sankar,
I have tried to re-produce the scenario by using sample code given above with a “Blank2007.mpp” and Aspose.Tasks for .NET 7.3.0. The error message “The imported data does not match the destination field type” was observed while opening the output file in MSP 2007, however no difference could be observed in the dates. Could you please share your code along with sample data which can be used here to observe the problem and provide assistance?
P.S. I would request you to discontinue this thread and start new thread for different issues like this one under discussion. It will help you, as well as us to follow the issue in a proper way.
