Hi Anuj,
Are you passing an output as xml? Quite a usual scenario in SP05 with xacute having multiple output parameters with one xml.
However,this should not be an ideal way MII responds, it looks like a bug.
I am personally waiting for some patch/fix for this one. Which patch are you using?
Workaround: You can create an xml document and append outputs so that you get a single xml output parameter from xacute out of which you can retrieve specific values.
Hope this helps.
Thanks and Regards,
Swaroop
