SUS PO Confirmation XML Generation

Hi Team,

I have an issue in my SRM SUS portal ,I have Message to purchaser texts for PO Response(Confirmation/Rejection).

So when ever if the PO's gets confirmed or Rejected , the reason behind,will be given in the Message to Purchaser texts.

Now the problem is as soon as the PO is confirmed an XML will get generated.

But XML is generating with out these text(Message to purchaser) details.So i want to debug why these text details are missing while generating the XML.

So is there any class which creates those XML's??

I cannot debug the whole program as its a big process.

So kindly let me know how simply can i do/trace this?

Thanks!
