XML Export -> can´t create XML output file

Hello,

I use a macro to start a report which create a XML file with some values. The report use the values and create a simple xml file. 
 

When I start the debug mode on the report, then everything works. It creates a xml file on following path:

C:\Users\****\Documents\ARIS 9.8

But when I start the report over the macro with "Report.execute(...)" -> then i can´t find any xml file. 

But  "xmlOutput.WriteReport()" return true, so the document has been successfully loaded...

Thanks!
