access privileges a job step is run.

None.

How to fix this error?

Have your user administrator give you an authorization for the user
named in the message. The required authorization object is <LS>Batch
Processing: Batch User Name</>.
You do not need any special authorization to enter yourself as the
"authorizations user." Your user ID is the default value for the user
field.
