System.CalloutException: IO Exception: improperly specified input name

Can anyone lend some insight as to what "improperly specified input name" is on this Exception?

I can't find a single thing on it.

We are getting this from an integration between SFDC and SAP PI.  This was a functioning interface 2 days ago and it stopped working abruptly.  I believe it's an SAP side issue, but we are just trying to find the exact cause for this thrown exception so they can fix it.

Any help in understanding the text is appreciated.  If more info is needed, please let me know.

Thanks in advance.
