SSIS: Use System::TaskName inside the dataflow

Question

For more detailed logging, I want to retrieve the [System::TaskName]

Right now, when starting from the task that fails we go to \'script task\', there I fetch [System::T

Answer 1

I was able to access the TaskName by adding the following inside a Script Component.

Private Function ReadVariable(ByVal varName As String) As Object
    Dim result As Object
    Try
        Dim vars As IDTSVariables100
        Me.VariableDispenser.LockForRead(varName)
        Me.VariableDispenser.GetVariables(vars)
        Try
            result = vars(varName).Value
        Catch ex As Exception
            Throw ex
        Finally
            vars.Unlock()
        End Try
    Catch ex As Exception
        Throw ex
    End Try
    Return result
End Function

and then accessing the variable like so

ReadVariable("System::TaskName")

Answer 2

From the looks of your data flow, it looks like you're trying to implement error logging. I've had good luck using an event handler for this sort of thing in the past. It has the added benefit of cleaning up your layout and making the maintenance of the package easier in the future as you don't need to maintain linkage from all of your tasks to the error handling.
