CIU5003E

Some action failed. Return/ABEND code=return reason=reason

A batch program was unable to complete because some action failed.
The batch program is terminated.
If some action is opening a VSAM file then check the return code and reason in the VSAM messages and codes manual to determine the cause of the error. If some action is opening a non-VSAM file then the most likely cause of this message will be missing or incorrect filenames in the JCL to run the job. Correct the JCL and rerun the job. If some action is GETMAIN or IEWBUFF then the most likely cause of this message will be shortage of virtual storage. Change your JCL to allow more and rerun the job.
