SAP PI 7.11SP11 EOIO Status HOLD although predecessor DLVD
We have a SAP PI system 7.11 SP11 and we use an ICO with EOIO on outbound side (EOIO forced by ABAP Proxy from ERP backend). We have the
symptom, that the first message of the queue is processed successfully and goes in status DLVD as expected, but all others stuck in status HOLD. If I "restart" the first HOLD message, it is processed successfully and goes in status DLVD, but again the next successor remains in HOLD. Thus each and every message has to be started manually.
Among other stuff we have read SAP notes 1058900 and 1004334, describing exactly the symptom we have, but they belong to XI 3.0 resp. XI 7.0 systems.
What's going wrong here? Any ideas?
Thanx in advance,
