Hi Laurel,

Its long time back and I don't remember now the fix I have got at that time. Would I have cared posting the solution then it would have been helpful to you now.

Anyways, for some reason I remember that I wasn't able to control this behaviour from SSRS design, instead I have changed the Source query accordingly to return the required number of columns only. So the source DataSet query would accept the Parameters and accordingly return only required columns.

But as I said, I really don't remember now the fix very well. I would be glad if this info is of any help to you.
