Problems receiving IDocs in Java after upgrading SAP to ECC 6.0
we use a Java application to receive and process WMTORD and MATMA05 IDocs from SAP. After upgrading SAP from 4.7 to ECC 6.0 the documentList delivered to the handleRequest-Handler remains empty. I have checked all relevant entries in the upgraded system (Distribution Model, Ports, Partner profiles) but I can't find any incosistences. The sender side seems to be ok (Status 03 in WE02, no entry in SM58).
Can anybody help?
