Portal MSS_SSO problem: HCM leave approval asks for login with Internet Explorer

Hi all,

I am hoping someone can shed some light on an issue with MSS leave request approvals.

We have just completed a set of SAP system copies to duplicate an existing landscape in order to facilitate creation of a spin-off company. the landscape consists of ECC6 and Enterprise Portal 7. the portal is only used for HCM ESS/MSS and uses ECC ABAP as UME and SSO logon tickets for back-end communication. SSO is working fine for everything in the new system except for MSS leave request approval where users are getting the following symptoms:

  • Manager goes to their team activity list and selects a leave request.
  • Leave request appears in a pop-up window and they can approve or reject it successfully.
  • User returns to the activity list and select another request but the pop-up window contains a SAP logon screen asking for user/password.
  • Attempting to enter the users own credentials does not work.

This behaviour will then continue until the user closes all of their Internet Explorer browser windows. If they then start a new browser session, they will be able to go back in and process one more leave request and then the problem happens again.

This problem happens with Internet Explorer (versions 8, 9, 10 and 11 have been tested with the same result). The problem does not occur with Google Chrome. The problem does not happen in the original system (the source of the copies) and leave requests approvals work fine there with IE.

The only technical difference that I am aware of between the old and new landscapes is that the old one uses the Sun/Oracle java engine but we had to use the SAP JVM for the new systems.

Does have anyone have any ideas or suggestions as to what might be causing this or any potential workarounds (apart from migrating to Chrome).

Thanks,

Kevin

Sounds strange...

- Does the internet zone change as well? That might be causing problems, so the application cannot access the SSO ticket again.

- Use Fiddler to see what happens with the MYSAPSSO2 cookie (your SSO ticket). Is it being destroyed?

- Check authentication scheme for that particular page. Maybe something is wrong with that?

Good luck!
