I have created a sharepoint 2010 reusable workflow using sharepoint 2010 designer. Here I have added Copy List Item action to it. Here when I am trying to add in the this list link. It is giving the below error.
The lookup that you defined is not guranteed to return a single value. If more than one value is returned, only the first value will be used. Do you want to continue?
Here my idea is to copy all items from one list to another.
