I would like to change the configuration of an assembly in a drawing view. (see picture)

I got a Assembly in my drawing which consist of configuration name 23 to 100

When i record a macro to execute this action this is what I get:

boolstatus = Part.ActivateView("Drawing View1")

boolstatus = Part.Extension.SelectByID2("Drawing View1", "DRAWINGVIEW", 0.14598639297934, 0.119923548387097, 0, False, 0, Nothing, 0)

boolstatus = Part.ChangeRefConfigurationOfFlatPatternView("C:\Sollas_Prod\Projects\014\PN014-0101\MRD00021_VO014-1765\Mechanical\00038294.sldasm", "24")

When i change the value of 24 to 25 the configuration should change to 25 (in red text color)

unfortunately this does not happen

Is there any other option to achieve this action?
