Hi (again),
I'm trying to use a field (which is present once in the read side) as parameter to be saved on each record of the write side.

I'm trying the GET/SET parameter with no luck...

any suggestions?


thanks again


P.S. please see the example attached, I'd like to replicate the field 'notes' of the read side to each row of the write side.

Hi Gennaro,

To set a parameter only on first row you have to use the following little script.
Code:
int count = 0; public object DoWork() { if (InValues.Length == 0) throw new Exception("one input parameter expected"); // only set the parameter on first row if (count == 0) Parameter.SetValue("first_number", InValues[0].GetValue()); count++; return null; }

Note: In the .NET Script Heater you have to switch the "Execute when" option to "Per each Row"

In the attachment you can find a brief example how to use it.

In one of a next version I’ll put this feature into the Set Parameter Heater, thanks for the request.
