Hi Bhavesh,
Thank you for your reply!
I will try to follow up your questions.
Just an additional point. In Boomi, as per my first post there are no errors visible. The process is finished successfully and I can only see one warning message.
The xml is above in previous post, but as the page was converting it I took out the < signal 
It looks fine in XML:
We are in the latest version where Axis framework has been installed as well.
