Thanks again for your help! This doesnt work for me.. Any other solution? I actually created a calculated date field which adds the data in two other columns. I am now trying to use this column to populate the gantt chart.

Hey Guys, same Problem here. We are setting up a Marketing Plan with a Startadte and a duration in weeks. We want to see the campaigns in a Gantt View. So we created a new calculated field with =startdate+(weeks*7) and Output as date. startdate and weeks are Required fields, so the new field enddate should be also required. While creating a new View i even can choose this new field for the duedate, but when trying to display the view. We just get the above mentioned error. Is there meanwhile a solution or did Microsoft provide a hotfix? Thank you in advance and kind Regards Rafael
