In WB Mechanical scripting, how can I change the transformation angles of an external data file?

import System
from System.Threading import *
 
def RunWBJN(cmds):
    def Internal_RunWBJN():
        import wbjn
        wbjn.ExecuteCommand(ExtAPI,cmds)
    thread = System.Threading.Thread(System.Threading.ThreadStart(Internal_RunWBJN))
    thread.Start()
 
def SetImportedLoadRotations(ImportedLoadGroup,XY,YZ,ZX):
    coord = ImportedLoadGroup.Source.Split(':')[0]
    WBcmds = '''
coord = "$coord"
import clr
clr.AddReference("Ans.UI")
import Ansys.UI
 
view1 = Ansys.UI.UIManager.Instance.GetActiveWorkspace().GetView(Ansys.ProjectSchematic.View.ProjectSchematicView.ViewName)
coord_map = dict(view1.CoordinateMap)
coord_map2 = {Ansys.UI.IDManager.GetAlphabeticLabelFromCoordinate(coord_map[key]):key for key in coord_map}
setup1 = coord_map2[coord]
externalLoadData1 = setup1.GetExternalLoadData()
externalLoadFileData1 = externalLoadData1.GetExternalLoadFileData(Name="ExternalLoadFileData")
externalLoadFileDataProperty1 = externalLoadFileData1.GetDataProperty()
externalLoadFileDataProperty1.ThetaXYUnit = '$XY.Unit'
externalLoadFileDataProperty1.ThetaYZUnit = '$YZ.Unit'
externalLoadFileDataProperty1.ThetaZXUnit = '$ZX.Unit'
externalLoadFileDataProperty1.ThetaXY = $XY.Value
externalLoadFileDataProperty1.ThetaYZ = $YZ.Value
externalLoadFileDataProperty1.ThetaZX = $ZX.Value
'''.replace('$coord',coord).replace('$XY.Unit',XY.Unit).replace('$YZ.Unit',YZ.Unit).replace('$ZX.Unit',ZX.Unit).replace('$XY.Value',str(XY.Value)).replace('$YZ.Value',str(YZ.Value)).replace('$ZX.Value',str(ZX.Value))#,YZ.Unit,ZX.Unit,XY.Value,YZ.Value,ZX.Value)
    print WBcmds
    RunWBJN(WBcmds)
 
 
impload = ExtAPI.DataModel.GetObjectsByType(Ansys.ACT.Automation.Mechanical.ImportedLoads.ImportedLoadGroup)[0]
XY = Quantity(30,'degree')
YZ = Quantity(0.2,'radian')
ZX = Quantity(0.3,'radian')
SetImportedLoadRotations(impload,XY,YZ,ZX)
