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