Import Integration Interface from excel file

Gurus - Need help!!

We are trying to import base override forecast into Demantra from an excel file.

We configured the interface from business modeler and gave all details like file type,file name,delimiter etc.

But when we try to launch the interface from Workflow Manager ,

It is erroring out with message : Invalid Command line.

We have the file in Windows machine and Demantra is installed on Linux.

Are we missing anything here?  Any special setup need to be done?

I found few metalink notes but none helpful.

Any help would be greatly appreciated.

Thanks,

Sam
