SAP GUI VBScript for data export results in empty document when run in VBA [excel]

Question

I have a VBScript that runs a data export from SAP GUI. If executed alone or in SAP it runs and results in an excel worksheet with the desired data.

However, I want to have it implemented in a VBA Sub. I found this thread that was already very helpful. When I start the macro in excel, it runs the whole script through SAP without error only to open the destination Excel file without saving the data to it. At first, I didn't realize it, but when I clear the document it is obvious that it is not being overwritten.

Also there is no error message showing.

Thanks in advance for your help.

By chance I ran into the same mistake with different consequences elsewhere. Long story short: It seems you can't use %UserName% when operating from Excel. Instead replaced it with this

SAP_session.findById("wnd[1]/usr/ctxtDY_PATH").Text = "C:\Users\" & Environ("username") & "\Documents\SAP\SAP GUI\"

Might help someone.
