how to convert from raiserror to throw in the current context?

I have a function that checks is the file is present on disk in an specific location . Using that function I am checking for the latest backup, in the code below. If we don't have a backup anymore, for a specific date, I want to raise an error. Currently I am using raiserror but because of Deprecated raiserror detection I would like to use throw instead . How can I do it? this is part of my stored procedure: IF @ServerNameToRestoreOn IS NULL THROW 50001, '@ServerNameToRestoreOn cannot be NULL - it must be the name of server\instance you want to restore the database to', 1 IF @Database IS NULL THROW 50001, '@Database cannot be NULL - it must be the name of the database you want to restore', 1 IF NOT EXISTS ( SELECT MAX(backup_set_id) FROM msdb.dbo.backupset a INNER JOIN msdb.dbo.backupmediafamily b ON a.media_set_id = b.media_set_id WHERE a.database_name = @Database AND a.type='D' AND a.is_copy_only = 0 AND a.backup_finish_date < @StopAt AND master.dbo.fn_FileExists(b.physical_device_name) = 1 GROUP BY database_name ) BEGIN SELECT @sql = 'The database called "%s" does not have a backup before' + CAST (@StopAt AS VARCHAR(20)) + @vCrlf + @vCrlf RAISERROR(@sql ,16,1,@Database) END How can I replace the raiserror by throw? I want to show the @Database and the @stopat in the error message or, in better wording: how do you pass THROW() a message where you can still use printf-style substitution like you can with RAISERROR?
