IDOC to SOAP - Multimapping - ends with EOIO

I send out IDOCs containing a lot of information (in my case 1000 Sales Orders) and I have setup following IF Determination

The result is perfect, as many Sales Orders in my source IDOC is creating same amount of SOAP calls for the target application. But in some rar cases, the SOAP call fails for single transactions and in this case all remaining messages are blocked as all messages are in same EOIO Queue.

Is there a way to avoid having the message in same EOIO queue? I want to send out EO.

Thanks for your help in advance.

Regards
