PLS-00306 dbms_scheduler.create_job
You need to review each of the parameters in the docs, located at https://docs.oracle.com/cd/E11882_01/appdev.112/e40758/d_sched.htm#ARPLS72300.  Specfically, take a look at 'job_action' for your specified 'job_type' of "STORED_PROCEDURE".

"The action is the name of the stored procedure. "  (emphasis mine).  You are saying the action is a command -- "execute". 

Also, does your procedure "delete_org_sre_package.process_org_sre_deletions" have any input or output parameters?
