Integration

Hi All,
We are sending the Outbound messages to IP_OUT_QUEUE, it gets picked up by the B2B,
but it is not reaching the trading partner. When I run the Business Message status report,
it shows all these messages are in the Invalid state.

We have cross checked all the b2b setups. It seems to be fine.
When I tried to change the header info such as From Party, To Party, Document Type Name, Document Type Revision
it says 'Cannot identify ..'. So I think the header data are correct.Can any one let us know what are all the other possible reasons for this Invalid state. Also help us,how to debug it.

Thanks,
Gowri.
