Thanks guys for your reply !!
@ Marie: Tried this report for that particular transaction, nothing happened. Can you please let me know why/how to use this report.
@ Rentas: we are using Processing category is 0002: order - contract - settlement and its running perfectly fine for all other transactions. First time we got this error, user did something while creating/settling of the transaction which I am not able to understand.
Thinking of reversing the this transaction and creating a fresh one but before that want to understand why system is behaving this way.
