Activating Activities in the CBS 
For the activation of objects, use the central build process in the Component Build Service (CBS). The activation is carried out if the process was successful or if the option Activate even if build fails has been selected.
The Component Build Service does most of its work automatically – usually all you have to do is start the processes. This also applies for the calculation of activities, which is a prerequisite for the activation of an activity, the predecessor activities. Such a dependency exists if a not yet activated activity contains objects of a DC, from which objects are contained in the activity to be activated.

You can set the predecessor check to overlapping files: In this case, only those activities are considered as predecessors that have at least one file in common with the activity to be activated.
The CBS executes these tasks:
· Central build
· Activating activities
This procedure is used in all development scenarios, in which the CBS is available.
· You have checked in your activities into the Design Time Repository. Your activities are now closed.

You can also activate your source files whenever you check in activities.
· The activation requires an authorization, which you have in two cases:
¡ You are the developer (with the authorizations of the group JDI.Developers or similar) and owner of all required activities.
¡ If this is not the case, that is, if activities of other owners are predecessors of the activity to be activated, then you can activate this activity only if you have the XDeveloper authorization. Usually quality managers and administrators have this authorization.
...
1. Open the Activation view under Window ® Show View ® Other... ® CBS Activation.
You see your closed activities.
2. In the context menu of an activity, choose Activate.
The Activation wizard appears. If an activity has dependencies to other DCs, the display shows it: In this case, you get a pushbutton Activate with all Predecessors; if there are no dependencies, you get the pushbutton Activate.

Select Calculate predecessor activities based ONLY on overlapping files only if you are sure that all other objects of your DC will be checked in in other DCs.
3. Choose Activate or Activate with all Predecessors.
A dialog window Activation Request appears.
4. To trace the build process in the Activation Requests view, choose Open Request View; otherwise choose OK.
The source files in your activity are now built centrally and activated. In this process, the predecessors of an activity are activated as well – however, only those that are required by the selected activity because it is built on them.
With the authorizations of a JDI developer, you are not allowed to activate the activities of other users. You need one of the following roles for activating activities of other owners:
· XDeveloper
· QM
· Administrator
For more information, see Roles in the Component Build Service.
In some cases, it may be necessary to activate activities by force. You need one of the following roles for enforcing the activiation:
· XDeveloper
· QM
· Administrator
For more information, see Roles in the Component Build Service.
...
1. To get this option in spite of a failed build process, choose Advanced on the Activation wizard.
2. Select the option Activate even if build fails.
3. Then execute the activation as described above.
For the source files of all activated activities, the CBS now contains runtime objects (archives). Your DCs are now available in the new or changed version in the Active workspace. You can use the Transport view of the Change Management Service to release them.
