Enumeration violation

Hi folks,

I created a dynamic list type attribute for a part where the project names are the values of the list. It works fine when I create new parts from Create New menu. Now I'm trying to use Import functionality to load lots of items but I'm facing the following error: "While performing Enumeration validation for 'Parts.Page Two.Project Name', the following message was received: Enumeration violation: value 'Project X' not found in the list of legal values for this attribute.".

Any directions?

My best

Carlos
