I have two lists : list A & list B. Both lists have identical schema and information. I have created a SharePoint 2010 designer workflow on list A ,which triggers when an item is updated in list A.
The workflow should basically check if the list item (in list A) being updated , exists in list B . If it exists, it should update it ( Call Update List Item action), else it should create a new list item in list B. Please suggest how can I check if the list item exists in list B?
