I'm looking for a way to set a default value on one comboBox when I open the report.

I found this Thread: working with combobox: Set default value with Macro
But it doesn't do what i want, it only duplicate a value at the top of the comboBox list:

How do I set a default value for the comboBox when I open the report, without losing the hierarchy? (something like this):
forum.jedox.com/index.php/Atta…88b7f4d06d3f8f0116b86cdac

I already have this Macro on the report:
forum.jedox.com/index.php/Atta…88b7f4d06d3f8f0116b86cdac
but it seems like it's not working. This happens when I open the report as client:
forum.jedox.com/index.php/Atta…88b7f4d06d3f8f0116b86cdac

By the way, the comboBox targets to the variable @cmbSolicitanteP and I want "TERC" as default value.

Txs for the help!
