Hi @databrick_enthu ,

The error is unfortunately misleading. The Materialized View / Streaming Table on Serverless Generic Compute is not yet available for a Preview.

 For now, you have two possibilities:

• Attach the notebook to a Serverless SQL Warehouse. This will create a Streaming table and a standalone Declarative Pipeline for it. You will find the pipeline in Jobs & Pipelines > Pipelines > Pipeline named ST-<table_name>
• Create a Declarative pipeline out from your SQL notebook. For this, go to Jobs & Pipelines > Create ETL Pipeline > Add Existing Assets (your notebook). Find the whole tutorial here.

Hope it helps.

Best regards
