JCLCM0206I job-number job-name ALLOCATION DEFERRED UNTIL OPEN - DDNAME

In the specified DD statement, the first (or only) data set specified does not exist and the step being executed is an IMS batch step.

Allocation of any data sets for the DD statement is deferred until data set open time to prevent generation of JCL errors for DD statements which may be associated with IMS databases, as they are not required by the IMS component.
