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.
When you delete an object (a dataset, attribute, and so on) from the LDM, the related objects such as measures or insights become invalid. Such invalid objects are not exposed in Analytical Designer or Dashboards. You can delete or fix them only through the API.
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.
