When trying to import (open) a project in Microsoft Project (MSP) from Clarity, the following error message is shown:
"An Import Error Occured. The element <ExtendedAttribute> in the <Task> element with <UID> = X has invalid data." (X can be any number).
Any Clarity and MSP environment (using Microsoft Project integration).
A possible cause for this is that a special character that is generally not accepted in a string attribute has been introduced in the project via copy/paste from another rich text editor (for example, Microsoft Word).
Examples include new line characters in attributes where this is not accepted, special characters such as tab characters...
If there is a new line character in an attribute where this is not accepted, check "MSP Import Error on extended attribute if the related text field in Clarity has a second line manually created".
Special characters may show up in the XML file and cause issues when being imported to Microsoft Project.
