About the Fetch Method on the Master Datastream

The Fetch method on the master datastream (QueryOuter in the example report) moves the data in the current master record to a public data row variable, called OutSideDataRow. This variable is defined on the master datastream, making the current master record available to the detail datastream, ssPositionQuery. The Fetch method on the master datastream contains the following code:

Function Fetch( ) As AcDataRow

   Set Fetch = Super::Fetch()

' If a row is returned, then assign it to OutSideDataRow Var

   If NOT Fetch Is Nothing Then

      Set OutSideDataRow = Fetch

   End If

End Function
