Error description
As documented by APAR PK28707, TWS z/OS can handle up to one minute in time discrepancy for JMRENTRY if the NJE node is different between the A2 and A3J tracking records. However, if the NJE node is the same, any difference in value between the JMRENTRY of the A2 record and the JMRENTRY of the A3J record will cause a CCUN error. There is no known reason for the JMRENTRY value to ever be changed once the job starts execution; however to make it easier to determine that a CCUN error has been caused by a JMRENTRY discrepancy, a new message will be added which will be issued to the controller EQQMLOG. If this message is seen, the appropriate action will be to set the indicated operation to complete status (by a manual change). Note the JMR (Job Management Record) values JMREDATE and JMRENTRY are stored by TWSz as EXRRDATE and EXRRTIME. Field EXRJSRDR is comprised of the EXRRDATE and EXRRTIME values. The JMREDATE/JMRENTRY values are not expected to change during job execution, so TWSz does not recognize the events as referring to the same job if they report different times. Since the A3J record is not processed, the A3P record will be SUSPENDED, causing CCUN status when the A5 record is received: EQQE036I JOB jjjjjjjj(JOBnnnnn) ENDED IN ERROR CCUN. PRTY=p, EQQE036I APPL = aaaaaaaaaaaaaaaa, WORK STATION = wwww, IA=yymmddhhmm Circumstances other than a JMRENTRY difference can cause a CCUN error, so the new message will clarify this.

Temporary fix
Comments
if an unexpected JMR time change (not caused by a route) occurred that affect job events and the discrepancy is <= 1 minute, a new message (EQQE206W) will be issued to describe the operation, the discrepancy measured in hundredths of a second and the event reporting the discrepancy. - - - THE FOLLOWING TWS FOR ZOS PUBLICATION(S) WILL BE UPDATED: - - - +--------------------------------------------------------------+ | | |TITLE: TWS for z/OS Messages and Codes SC32-1265-02 | | | |Chapter 9.
