Hi,

I have created a SharePoint 2010 workflow for a tasks list that updates a list item column if the Date Complete <= Today's date & Percentage Complete = 100%

I used 'Set Field in Current Item' in the workflow & the values are updated in the list for the current item.

However, when I open the tasks list in MS Project Professional 2013 from SharePoint 2013, then I get a error "We can't write task - taskname to the SharePoint site. This is either because tasks list is in read only mode or because this task has a column that requires unique value."

If I remove the 'Set Field in Current Item' in the workflow, then the error does not occur. However, the 'Set Field in Current Item' in the workflow is required.

Please provide solution to this issue ASAP. Your reply will be greatly appreciated.

Thanks in advance
