file to file scenario; URL missing at the receiver.

Hi,

i have  file to file scenario; Note:my sender file structure is XSD convereted from IDoc.

the file runs fine end-end; but at the reciever side the output file is missing URL: "xmlns="http://www.wbf.org/xml/b2mml-v02"  

do i need to add this manually in the mapping?

or is there any settings i have to do in IR or ID.

right now at receiver side i'm getting the root node as <ProductionSchedule>

but expecting it come as <ProductionSchedule xmlns="http://www.wbf.org/xml/b2mml-v02">

Thanks in advance.
