Diagnosis
The segment type &v1& could not be read for the message type &v2&.

System Response
Either there is an error in the program that created the IDoc, or someof the settings in the ALE distribution model or the ALE segment filterare incorrect.

Procedure
Make sure that no filter objects have been specified in the ALEdistribution model for this message flow and that there are no entriesin the ALE segment filter for it either.
If this does not fix the problem then you should at least now get anIDOC with a syntax error. You can obtain more information about thisfrom the status records of the IDoc.
