Symptoms:
Concurrent request completing with Warning status.
 
Error:
The Concurrent Request logfile show the following error:
-- PUBLISH:
oracle.apps.fnd.cp.opp.PostProcessorException: oracle.apps.fnd.cp.opp.PostProcessorException: oracle.apps.xdo.oa.schema.server.TemplateNotYetValidException: START_DATE is still not coming yet.
 
Cause:
Having different date/time values on EBS nodes causes the run time error.
Make sure that all the EBS nodes have the same date/time settings.
In our case, the year was incorrect on the application server.
 
Solution:
Change the date on the appropriate server with root user.
[root@ebsapp01 ~]# date -s "12 AUG 2018 13:40:00"
 
Resubmit the concurrent request and it should complete successfully!
