Hi,
Looks like there might be some values missing in the IDoc as per xsd..
As the new Idoc adapter IDoc_AAE does a validation of the IDoc against the xsd..so check the Idoc generated is as per IDoc xsd.. like segment should have value 1 as per xsd..else will end up getting the above errors...
This is the new feature of the idoc_aae adapter..
HTH
