Thank you amrute for your reply. You are right we do faced similar issues in many other occations and sent exact data and could resolve the issues. In this case also we have given in exact format for all fields. Date format as given in this case is same as what was given in another working XI scenario. However I look at the data type of date to be sure.
As you see the message is regarding partner and partner function. If you have any other point of view may please be indicated.
