Hello,
When a Process MEC BOD has an error, it normally generates a Acknowledge_Error_Out BOD. It is mandatory to create a Acknowledge_Error_Out when creating a custom Process BOD.
My question is how we retrieve the Acknowledge_Error_Out in Dataflow/ION Desk because it has the same Noun as the normal Acknowledge BOD from the Process BOD. 
The Acknowledge_Error_Out has a Confirm BOD as input.

Thanks.
