HI

We are on Portal 7.4 and ECC EHP7, basic setting for UWL config under System Admin in Portal has been done, apart from that no other changes been made in SWFVISU and to the properties of PCD objects in Portal.

Working : Leave request respective to the Manager are appearing under UWL

Not Working : Clicking on any ling from UWL taking us to the same screen for leave requests.

SAP_ALL authorization has been provided to the user.

From HTTP TRACE I have found that WI_ID has been passing and it;s different for each link.

ex : /irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultAjaxframeworkContent!2fcom.sap.portal.standalonecontentarea?NavigationTarget=OBN%3A%2F%2FBOTechnicalName%3Demployee%2FOperation%3Dapproveleaverequest%2FBOSystemAlias%3DSAP_ERP_HumanResources&DynamicParameter=Operation%3Dapproveleaverequest%26BOTechnicalName%3Demployee%26wi_id%3D000000385118%26BOSystemAlias%3DSAP_ERP_HumanResources&PrevNavTarget=navurl%3A%2F%2F0e1456b4e0492c0d4a8d1286382b9d86&sap-obn-url=OBN%3A%2F%2FBOTechnicalName%3Demployee%2FOperation%3Dapproveleaverequest%2FBOSystemAlias%3DSAP_ERP_HumanResources&NavMode=1&CurrentWindowId=WID1420964796369

Hi Mohan

Many thanks for the response and update.

In relation to your analysis findings you outlined the following exceptions being encountered:

  • java.lang.Exception: Problem occured while creating JCO client for destination: SAP_ECC_HumanResources

In relation to the above kindly review and reference the following:

Regarding this issue and the scenario that you are encountering your points of analysis regarding SAP Note 1133821 was correct as the UWL Destination Service Configuration is important to review.

The RFC destinations have to be maitained so that the UWL can make functional calls to the backend applications. I believe on your system somehow the calls to the backend fail and thus you may need to check the configuration of the RFC destination as per the note.

Check that after applying Note 1133821 the destination names and the UWL connector names exactly match, even considering case-sensitiveness. If your portal system alias (=UWL connector name) is for example XYZCLNT100, then the rfc destination name should be exactly XYZCLNT100$WebFlowConnector. Please correct the rfc destination accordingly.

After you have checked/prepared the RFC destination for the future use please delete that connector in the UWL config UI (Portal->System Administration->System Configuration->Universal Worklist) with which you would like to use this RFC destination.

After that

- restart the portal cluster

- recreate and reregister connector

Now retest.  Are you still seeing the issue?

Kindly update me as per your findings.

Kind Regards

Hi Mohan

I hope you are well and many thanks for using the SAP Discussion Forums .

In relation to the scenario that you have described you mentioned the following:

  • You are on Portal 7.4 and ECC EHP7, basic setting for UWL config under System Admin in Portal has been done, apart from that no other changes been made in SWFVISU and to the properties of PCD objects in Portal.

  • Working: Leave request respective to the Manager are appearing under UWL

  • Not Working: Clicking on any link from UWL taking us to the same screen for leave requests.

Now based upon the extract you provided from the HTTP Watch Trace have you captured a default trace error log file yourself to ensure there are no accompanied underlying error exceptions?

What is interesting here is that you mentioned no other changes apart from the upgrade have been performed.  So what we should have here is a decision task that then launches either a Web Dynpro ABAP or a SAPGUI or in turn raises an event.

Kindly capture a trace and let me know if there are any underlying exceptions appearing.

Kindly update me as per your findings.

Kind Regards

HI

Cache has been cleared many times,

clicking on leave request tasks generating url with above format but with different WI_ID.

But all links shows same request details which is the latest one from the list.

Thanks
