In this chapter, we explained the Contributor workflow process, explored the roles of the reviewer and the planner, and also explained how the current status of the forecast cycle can be monitored by using the Contributor workflow screen. We then showed you how to log on to and navigate in the Contributor Web Client. We also explored how the entry of planning data can be facilitated by the use of copy and data commands. Additionally, we looked at breakback, working with annotations and documents, exporting data from and importing data to the client, data validation, Contributor for Excel, and working offline. Finally, we explored the new Contributor Web Client that was released with IBM Cognos 8 Planning 8.4.
