Introduction:
When submitting a job against CA View and/or CA Deliver, the job is abending with a S306
Question:
What might be causing the S306 abend and how can they be prevented?
Environment:
z/OS
Answer:
The S306 abend is usually caused by some type of APF AUTHORIZATION problem on either a library or a program.

Things to check would include: 

1. Make sure your CA View / CA Deliver load library is APF AUTHORIZED.
 
2. Make sure ALL libraries coded in your jobs STEPLIB concatenation are APF authorized. If any 1 of them is not authorized, it would render then all unauthorized.

3. Verify that you have not recently linked an unauthorized module or exit into your CA View / CA Deliver load library.
