Financial Management server clusters are an efficient way to push specific job types (such as consolidations or reports) to servers best suited to handle them. Clusters can also be used to separate user groups, like standard users and administrators. An issue arises when HFM clusters are mixed with task flows.
When an HFM application is registered via Consolidation Administration it is attached to a User Management Project as well as a Cluster. Registering the app immediately changes the cluster preferences of all task flows attached to that application. This means if the task flow was originally configured to run on a specific cluster, registering that app will change the configuration to point every step that references that application to the selected server cluster. Creating multiple copies of the same task flow that points to different clusters is not possible at this time. All copies will be changed as soon as the application is registered.
