Requirement is to restrict the list of values from the Projects of a BU, currently when creating a purchase order the user has access to the full set of values of a particular business unit. The requirement is to limit the projects which are displayed, considering there are more than 1000+ projects per Business Unit and there could be 100+ users creating documents. For example, we need user A only to have 10 projects displayed for them to charge against the project, while user B needs to have access to only 5 projects.
