Publish a Logical Data Model
When you are done with building the logical data model (LDM), publish it to the workspace. Publishing the LDM replaces the current LDM, if any exists in the workspace, and makes the LDM entities available for being used in insights.
Click Publish in the top right corner.
The publishing dialog opens.
Click Publish in the dialog.
The publishing process starts. When the publishing completes, you see a message that the LDM has been published.
Once you have the LDM published, you can start building insights and dashboards.
