XML Publisher error -Unable to find the published output for this request

This is one of the most common issues when you try opening the output of an XML Publisher report output from the SRS screen.

As shown in the below screenshots, when you try to open the XML publisher report output you get below error,





When you see this error, check the concurrent request status.
There can be two possible reasons (that's what I could find yet),

1. If the Concurrent request goes to Warning status,
Check the log file. You would see a message something like this,

+---------------------------------------------------------------------------+
Start of log messages from FND_FILE
+---------------------------------------------------------------------------+
+---------------------------------------------------------------------------+
End of log messages from FND_FILE
+---------------------------------------------------------------------------+


+---------------------------------------------------------------------------+
Executing request completion options...

+------------- 1) PUBLISH -------------+
Beginning post-processing of request 26431776 on node xxxxxxxxyyyyy at 02-MAR-2010 20:36:43.
Post-processing of request 26431776 failed at 02-MAR-2010 20:36:43 with the error message:
One or more post-processing actions failed. Consult the OPP service log for details.
+--------------------------------------+

+------------- 2) PRINT -------------+
+--------------------------------------+


If this is the case then check the OPP log file located at following location in DB tier,


This happens if the XML data source and the XML Publisher template are out-of-sync i.e. if OPP does not find a perticular value in the XML data then it throws out this error. Check your template if it has all the valid XML elements in it and correct it if there is any difference.


2. Concurrent request completes normal but still there is no output and you get the above error. If this is the case then mostly the layout has not been setup properly prior to this request submission. You can see from the below screenshot, the layout has not been setup correctly.



There is a bug in Oracle wherein even if you set the layout parameters, it does not take. If that is the case then enter the layout parameter and then just re-enter the language setting by clicking the "language" button in the SRS screen.
And then submit the request. Now the report should get generated and you should be able to open the output.
