I have an Execute SQL Task that returns a dataset to variable DfltValData. A dataflow follows that with a script component that access that dataset (read only variable) (see code below) and everything is fine. Now, after that, there's another dataflow with a script component, with the same code as below, trying to access DfltValData. Here is where the problem is, the DfltValData object does not contains any row. Whats happening and how to solve this?
Thanks!
Dim olead As New Data.OleDb.OleDbDataAdapter
Dim dt As New Data.DataTable
Dim row As System.Data.DataRow
olead.Fill(dt, Me.Variables.DfltValData)
For Each row In dt.Rows

.HAHAHAHA!! Not to laugh at your problem, but search a bit and you'll find a VERY recent discussion on this very topic.|||http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1406350&SiteID=1|||Use a MULTICAST if you need to work with same rows again.
There is a code work-around (shown in the forum post Phil referenced), but it's ugly.

If the basic problem is that you want to reuse the data in another data flow, you could use a multicast in your first data flow, and output the data to a raw file. Then use a raw file source to pull it into your second data flow.

Exactly. Or simply use a multicast to populate 2 variables in the first place with exactly the same data.
