Insufficient records in Vuser details view while running through Performance Center


I am using a .dat file that has the parameter settings as: Unique, Each Iteration, and Continue in a cyclic manner. This should theoretically never actually run out of data because it should be reusing the data. However, after every line is used up, the rest of my iterations fail out because of an insufficient records error in Loadrunner.

"Error Message :error insufficient records for parameter 'xx' in table to provide the vuser with unique data

Is there some special setting I need to use to get loadrunner to recognize these parameter settings in VuGen? or there any other setting i should use ?

P.S. I am using Performance Center for running my scripts with 100 vuser divided between 2 scripts .
