How can I solve extension _R tables failing to create? 

I am working on the old project Now.

This project was copied from another project repository.

Environment: Sandbox

Version: 20.10.36.64

Data Source: Business unit

Provider: SQL Server Data Source

The connection with the Data source is good and synchronized well.

When I am deploying the tables in ODX storage getting an Error.

An error occurred during create a table. See exception details for the failing object: Create failed for Table 'BSA.BSA_dbo_Inspection_R'.
An exception occurred while executing a Transact-SQL statement or batch.
The specified schema name "BSA" either does not exist or you do not have permission to use it.
