When I add new nodes to a completed workflow, EM sometimes reruns some or all of the completed nodes in the workflow, instead of running the new nodes only. Does anyone know how to prevent the completed nodes from rerunning?
Can you let us know what release of EM you are using and the configuration. The predecessor nodes should not re-run unless as noted that are flagged by the user or a change in one of the nodes upstream has been made. It may be best to file a support track on this http://support.sas.com/ctx/supportform/createForm . Sorry that you are having this problem .
I have set the data and SAS code nodes to not to rerun, but it still happens sometimes and I am not sure about the cause. When my workflow has the Start-End Groups, the rerun will only produce partial output.
