This example will show the necessary configurations for a workflow sending UDRs to ECS, and for a workflow configured to collect this data. The UDRs sent to ECS will have an Error Case, that is, a string associated with the Error Code.
Typically, a UDR may be sent to ECS as a result of a failing table lookup evaluation. To make sure that the error was not temporary and that the tables simply needed to be updated first, these UDRs are recycled. A new workflow is created, collecting them from ECS and reevaluating the same table lookup. If the problem still exists, the UDR is sent back to ECS.
