15-design-semantic-model-scale.md - Can't create semantic model because tables do not exist (yet)

Lab/Demo: 15-design-semantic-model-scale.md

Task: Create a semantic model

Description of issue

All of us in class are getting an error when creating the semantic model.

Something went wrong

We cannot refresh this semantic model because one or multiple source tables either do not exist or access was denied. Please contact a data source admin to verify that the tables exist and ensure that the owner of this semantic model does have read access to these tables: '<oii>dimcustomer,dimdate,dimproduct,...</oii>'
Please check the technical details for more information. If you contact support, please provide these details.

There seems to be some delay from finishing the Create-Sales-Data notebook and when all the tables have actually been created. We are seeing the delay inside Skillable's virtual machines and from a desktop machine.

Perhaps the lab needs to have a note to wait 5 minutes before starting this step?
