Monitoring Project conditional schedule

Hello,

I have a monitoring project, and inside, there is a table (operations). This table is populated by ETL daily, and every day the ETL job finishes at a different time. That's why I can't assign a specific schedule to this monitoring project. There is another table (job_status) that shows the condition of the ETL job. Inside that table, there is a column named 'Status of ETL JOB'. If the value in that column is 'Completed,' then it means the job has completed, and now the monitoring project can be run. How can I create such a schedule for that MP?

I would be grateful if you can help me.

Thanks in advance.
