Assigning Software Components to a Build Variant 
You have configured a build variant and want to assign it to software components (SCs).
You are in Landscape Configurator.
You have configured a build variant.
You have selected the relevant track and you are in change mode.
To assign one or more SCs to a special build variant, proceed as follows:
Choose the Build Variant tab page.
Select the build variant to which you want to assign the software components.
Choose Assign SCs ... The Assign Software Components to Build Variant dialog box appears. The table header shows you the selected software component and its validity in the track. The Software Components dropdown menu shows you the selected SCs that you can assign to the build variant.
Select the relevant SC in the dropdown menu and choose Add. The SC is entered in the table.
Note
You can also use the Add All function to add all SCs from the dropdown menu to the table in a single step.
Repeat the previous step for all SCs that you want to assign to the build variant.
Choose Finish.
Save your changes.
You have assigned one or more SCs to a build variant. The next build in Component Build Service (CBS) will build the SC in this build variant.
