Portal Request Failed (Fault returned {0})

Hi All,

I use WSDLs created from XI which inturn executes BAPI's in R3 and returns me the output/response. Two of such WSDLs are throwing this error.

<b>Portal Request Failed (Fault returned )</b>

Have any one of u come across this error in VC storyboard??.. Do let me know your experience and views on getting this resolved.

Thanks,

Kavitha
