About the deliver operation
In UCM, you can deliver your work as activities or as baselines. Typically, in a single project environment, you work on activities and deliver your completed activities. Some UCM environments manage parallel work on the same components. The project integrators in such environments deliver baselines to the project integration stream to incorporate changes in components.
You can deliver your work as activities to either the default target (the parent stream of your development stream) or a nondefault target. The policies on the project and on the target stream determine what target is allowed. When you start the deliver operation, the target stream policy settings are checked to determine whether the deliver operation is allowed. The project policy determines the settings for streams in the project; the project policy might defer the setting to the target stream policy.
If your organization uses HCL VersionVault MultiSite and your site does not master the target of your delivery, you can only post your work.
