Easier Updates – Monthly Update Assessment Report

Following the release of the new Repository Update process in the Siebel CRM 26.1 Update, a new enhancement to this process is the Monthly Update Assessment Report.

The Monthly Update Assessment Report provides insight into the impact of running RepositoryUpdate without executing it. This allows Siebel implementation teams to know in advance what is going to change, where the critical conflicts will be, how it will affect their usage of the application, and have a sense for the level of effort involved to merge the changes provided by Oracle with their customization.
