Unable to preview data in flat file destination which takes data from oledb source .Columns are correctly mapped with no error

Hi ,

I have a dataflow task which gets data from a openquery using oleddb source task and then dumps the data in a flat file .

In the editor of oleddb source i can preview the data coming from the oledb source and can the sample 200 records where as the flat file destination where in the data flows when I open and try to preview it doesnt show any records .

All columns are correctly mapped there is no errors in mapping but i cant preview the data in flat file destination editor.


What might be the issue ?

Thanks
