IDOC_INBOUND_ASYNCHRONUS - Alternate idoc fails

Hi All,

MII Version 15.3 SP0

I am facing a strange issue while sending IDocs from SAP to MII system. All the alternate Idocs are failing, I mean to say one will be success and next one fails , again 3rd is success and 4th fails. The error (attached screenshot) is common one we see at SM58 tcode as well as in Netweaver log. I wonder why only alternate idocs are getting failed.

Error Message.

java.lang.RuntimeException: Bean IDOC_INBOUND_ASYNCHRONOUS not found on host xxxxx, ProgId=XMIIIDOC01: Object not found in lookup of IDOC_INBOUND_ASYNCHRONOUS

Thanks
