Dear Ankur,
Please let me know bout the solution to this question. I did so many configuration settings in SPRO, but still error message is popping up "Item Category Not Defined". If it's possible to send the screen shots for the solution, please do that. I am unable to proceed further coz of this error. My mail id is : vrmanisowmya@gmail.com
I'll reward your answer accordingly.
Thanks,
Sowmyesh Maniyar..
