Hello Colin

We had the same issue. If you want to use a router:

- You have to set the Response From property on the router with name of the operation.

- Make sure to set Forward Generated Response To Target(s) to true
- The Response timeout. Do not set the Respone timeout on -1 because the system could hang if you have an error on the router.

-  Make sure that all the reply action codes (router and operation) are set in a way the system does not retry.

This way you can also use a router.

Kind regards

Hello Julian

Thanks for your clear answer, I will discuss your answer with my team. The proposal to filter in advance on trigger event in the main router is very interesting and is a good middle way. It's a way to keep the complexity in the systemrouter, but to do an easy filter in the main router. And it is still very maintainable.

Kind regards

The purpose of the first mapping is to do some transformations on the messages that are necessary for all the other systems. So we consider them as default transformations that's why we need a first mapping. Thank you for your advice
