Add a Step to a Branch
You can add customization types such as "Extend a Dimension" as a step to an existing unapplied branch or a new branch that you create.
Add a Dimension
You can create a custom dimension, join it to the ready-to-use or custom facts, and add the custom dimension to any subject area to meet your business requirements.
You see a message that your step is being applied to the customization branch. After it's applied, you see the new customization step in the customization branch. You can now apply the customization branch to the main branch or edit it to add more steps.
Note:
If you’ve created Add a Dimension steps using the previous functionality, you can still edit and reapply through the Edit option.Extend a Dimension
Extend ready-to-use dimensions with additional attributes from another data source.
