SYMPTOM:
When a user runs a document in Strategy Developer 9.4.1 or 10.x, the following error will show:

The data set is not ready in the document instance. This action cannot perform on the document instance without data set.

Look at all the reports that are returned in the search and right click on each and go to the properties. From there, locate either the user or the group the user is apart of and make sure they have access to the report. In this example, the user, "test", was initially given "Denied All" access. Giving this user "View" access resolves the issue.
