Wierd issues in UWL when used with Light Desktop

[Former Member]

Hi,

I have set up a UWL iView within a light desktop (with a light framework page). When I launch any workitem, I 'sometimes' encounter an error - System Alias is not defined or permission denied for this user. I ran the trace for the request and found that the UWL 'sometimes' calls the following as one of the URL parameters -" &System=ECC_ED1' title='UWL - Launch SAP Transaction" and thus is unable to recognize the system object as it reads the entire string as the system alias. The error log is as follows

com.sapportals.portal.appintegrator.ApplicationIntegratorException: Unknown system alias.

System Alias: 'ECC_ED1' title='UWL - Launch SAP Transaction',

User: 'TESTVIEW',

Reason: System Alias is not defined or permission denied for this user

The wierd part is that sometimes it just works fine without me having to do anything and once I get it working I do not encounter the error again. Also, the config works with no issues if I have everything on the Default Desktop instead of the light desktop. I am on Portal 7.3. I just wanted to know if anyone has experienced this issue before and if yes, is there a solution. I have tried searching for notes on this issue but didn't come across a relevant one yet (Read the following - 853509, 877188).

Thanks,

Prathamesh

Dear Prathamesh,

I do not find any specific to the UWL in external facing portal.

You may refer to the SAP Note 916545 - Central Note for External-Facing Portal and check the RESTRICTIONS in Light Framework Page.

Also check the UWL iview and properties as applicable with the note.

I think it will support fully in the light framework page.

Hi Arun,

Even I did not find anything specific to UWL on the light framework page and assumed that it should behave properly. However, the peculiar thing is that it works fine after a few attempts. That is what is bothering me. Either it should work or it shouldn't. I had read the note you mentioned to check the limitations of the light framework. The only caveat that I can see is that they recommend all web dynpro applications to be shown on a default framework page and UWL is web dynpro based. So, that could be an issue.

Thanks,

Prathamesh

Dear Prathamesh,

If UWL ivew is web dynpro based iview then it will not work properly. webdynpro iview are supported with default framework page in the external facing portal (light framework page)

You may try accessing SAP portal through fully qualified domain name.

Also look into SAP portal URL is in SAP recommended format. refer to SAP Note - 654326 Domain restrictions in a portal environment and SAP note 654982 URL requirements due to Internet standards

Hope it will helps
