Hello Sathish Pallem,
First of all, the way you explained the issue with all the screenshots is really impressive.
As mentioned by manjunath, please go through the sap note.
Also, go through this important note of yours when administrator can process the request and the user is not able to, did you happen to check if there is any authorization missing for the user?
Try giving maximum access to the user and process it and if things are moving normally then you can easily find out what authorization is missing for the user.
Please do the findings and keep us posted.
Regards,
Rakesh Ram M
