Resource Allocation is available in Project Request Manager. It is not included in the navigation by default however. This topic outlines the steps you can follow in order to add it.
1. Show Tabs: Link to the resource allocation page.
2. Update Quick Launch: Make navigation easier.
In the Page Group column, rename Requests(Hidden) to Requests. This will cause the link to display in the tabs on the Project Request Manager Home page.
