We have recently experienced some network issues which caused the IDoc's to stop flowing outbound from ECC to MII Message Listener. This happened 3 times during a network switch reconfiguration. 2 of the three occasions the MII Message listener had to be restarted on the MII server in order to get data to flow again. Interestingly some of the IDocs that were generated during this outage time were processed by the message listener and some didn't.
We are running MII 12.0 sp11 and ECC 6.0. The ECC server and MII server are located in different geographic locations.
When we look at the ECC system in WE05 we see only sucessful status for the IDoc messages saying the Data passed to port OK.
When we check the Message listener on the MII end there it only shows processed successfully. There are no failed messages or messages without rules.
Where can I check further to see the IDocs that really didn't make it to be processed by the Message Listener on the MII server?
Also is it possible that these IDocs that got lost somewhere are still sitting on the ECC or MII servers somewhere where we can re-process them?
And the Last question is, Why didn't the Message Listener handle the network issue automatically instead of needing to restart it?
