Hello Sikou KOÏTA,
Welcome to the Microsoft Q&A forum.
<copied from the documentation page>
Can you please follow the below and see if it helps?
After scanning your Snowflake source, you can browse data catalog or search data catalog to view the asset details.
Go to the asset -> lineage tab, you can see the asset relationship when applicable. Refer to the supported capabilities section on the supported Snowflake lineage scenarios. For more information about lineage in general, see data lineage and lineage user guide. https://video2.skills-academy.com/en-us/purview/register-scan-snowflake#lineage
Also, please see this known limitations.
- When object is deleted from the data source, currently the subsequent scan won't automatically remove the corresponding asset in Microsoft Purview.
- Stored procedure lineage is not supported for the following patterns:
- Stored procedure defined in Java, Python and Scala languages.
- Stored procedure using SQL EXECUTE IMMEDIATE with static SQL query as variable.
I hope this helps. Please let me know if you have any further questions.
