System alias SAP_LocalSystem

[Former Member]

Hi,

the predefined built-in system alias SAP_LocalSystem is used by the portal, e.g. to launch UWL and POWL.

Can anyone tell which information (profile parameter, definitions ....) is used by the portal to 'define' the target url of the Alias ?

In one of our systems the URL for e.g. the UWL iview is generated for a different server name and we can not find the place with the wrong definition.

Thanks Andrea

Hi all

I would also recommend the following reading:

1739698 - Security warning for mixed secure and non-secure content when accessing the UWL

This KBA describes a problem involving a security warning popup which might happen, but the actual root cause is shared also in your case.

All of that cases happen exactly due to the usage of SAP_LocalSystem system alias, which is resolved by means of following methods (according to Tal Haviv above):

--------------------------------------------------------
- servletRequest.getServerName();

- servletRequest.getServerProtocol();

- servletRequest.getServerPort();
--------------------------------------------------------

Depending upon the scenario (using Load balancer? Using reverse proxy?), it might be the case that these methods return the internal portal protocol/host/port, instead of the external protocol/host/port.

In such a case, you need to configure your system so that it 'knows' the protocol/host/port from the browser point of view is the external ones and not the internals.

SAP KBA above guides you through the way to achieve that.

Kind regards,

Hi Brent,

If you are using an FPN scenario you might have to create a different Alias for your local system and point the UWL to that system alias.

Hi Andrea,

Did you ever find out how/where SAP_Localsystem is defined?  If not, were you able to find a solution to your problem?  We are also having an issue with URL's not being generated properly for our UWL and we suspect that this value could be causing or contributing to our problem.

Thanks,

Hi,

Can you please check the system alias property specified in the UWL connector and check the system object properties for the target system.

Also, check the RFC destination maintained in VA or NWA for the target system.

Hi, thank you for your replies. SAP_LocalSystem is a default system being created to point to the same portal, it is hardcoded by SAP so there is no corresponding system definition . But the information about the host has to come from somewhere, (e.g. somewhere defined in config tool), but I can not find the place. We have an issue in SRM scenario because the alias SAP_LocalSystem is dissolved with the wrong hostname.

Hi,

The Local System is taken actually from the request that is coming.

From instance the server name is taken using:

servletRequest.getServerName();

So there is a need to perhaps check the requests, is it indeed coming from Portal request...
