IBM has provided us with a document to guide us through the Cognos installation with Maximo 7.5. You will need an IBM ID to view it though. [IBM Support]
Within the Maximo® Base Services 7.5 Releases, an IBM Cognos ® Reporting Integration is enabled. This integration extends the current suite of reporting tools that Maximo enables. This document details the installation steps required for the integration, the synchronization of the security groups, enabling of Maximo based Object structures to be published as Cognos metadata packages, and creation of Cognos Namespaces.
