I am trying to update a sharepoint list and getting the below error which doesnt make sense.
Error: SharePoint List Output (8): Error while updating records: Item does not exist. It may have been deleted by another user.
The workflow joins data between the same sharepoint list and data in a excel file and updates the same sharepoint list. The excel file has rows with data for all columns, where as the sharepoint list has data for few columns and this update should add the missing items for columns in the same sharepoint list. Am I doing anything wrong here?

AThanks
