I trying to get ACK back from the destination to the sending system.

I configured the Business Services to Ack Mode Application but sending system is getting Ensemble generated ACK [7] not destination ACK [9].

This is Ensemble 2018.1.1.312.0.

Ultimately I would like a NACK back when I have a Business Rule that blocks a messages from sending to Business Operations but currently [5] is an ACK |AA

|.

Does anyone have experience in creating a Business Routing Rule using Exists function?

I've used the comma delimited 'In' function, but I would like more manageability. Entering and remove items from a look up table would be much easier to manage then changing the comma delimited string.

Messages go to error state.

Any help would be appreciated.

This is my first post, so if I am doing anything wrong please let me know.
