How to pass multiple parameter to SAP Gui transaction from WD

Hi Guys,

I would like to start an SAP transaction from WD.

I construct the following URL:

http://my_server/sap/bc/gui/sap/its/webgui?~transaction=FMZ3%20KBLD-BELNR=0000667431?KBLD-BLPOS=6

The issue is that the first parameter 667431 is passed into the first field but the second parameter is not.

I tried many options but nothing works for the second parameter.

Any ideas?

Thanks,

Itay
