As this is your first post, please look over the following.
When you have a question, a new topic should be started - especially when the new question does not relate to the existing topic. I've split your question from the "dataset availability" topic, creating a new topic , so people will be able to see your question.
When you post a question, you should also post the jcl from the problem run and any error messages presented by the system.
You will also want to become familiar with the system messesges manual (linked to from this site via the "Manuals" link at the top of the page).
To get good answers, you need to post all of the info available.
Look up your error and let us know if you have any questions.
