S913 - You are trying to access a dataset which you are not authorized to use.
Check all the DATASETs in your jobs, there may be such datasets on which u dont have access. Let me know if i am wrong
I agree with subhasis.
Also check the disposition of the data set for which you are facing this
For example a data set on which you have only read previlage and you
try to modify its content you may face this ABEND.
