Invalid Data Type Exception Error in SAPBC

Hi All:

We are using SAPBC as our middleware for communication between SAP and external billing application.

We are trying to send PO in the form of IDocs (ORDERS) from SAP to the external application through SAPBC.

The message type ORDERS in SAPBC has a "rolled back" status indicating that there is some error.

The error we are getting in this case is:

"com.wm.util.coder.InvalidDatatypeException: com.wm.lang.xml.WMDocumentException: Received null IDocXML document"

I spoke to our technical lead who is responsible for maintaining the external billing application. He told me that there is no problem with his systems/servers/external application and that it is some internal problem with SAP and SAPBC.

This maybe an inappropriate forum to post this thread, but we dont have a forum for SAPBC.

We need to fix this asap. Any help in this regard will be highly appreciated.

Thanks,

Vj
