> Hello all,
> 
> I have a problem with the e-mail messages created through Workflow
> Notifications. The productive landscape is a central instance under which two
> application servers reside; <sapp1> and <sapp2>. The fully qualified names for
> these servers is <sapp1.company.com> and <sapp2.company.com>. 
> Users connect to the central instance through Citrix, and eventually get
> assigned to one of the instances. When a workflow notification is created,
> the links use the fully qualified server names in port 8000; so, the links
> start with <http://sapp1.company.com:8000/...> or
> <http://sapp2.company.com:8000/...>.
> 
> The problem is that all HTTP traffic is served through Web Dispatcher at
> <http://sapwebdisp:8100/...>, so all HTTP requests should start as such.
> 
> I have attempted to fix this in the following ways:
> 
> 1.	Setting the icm hostname to sapwebdisp; this would work on a landscape
> with one instance, but not on the aforementioned landscape with two
> instances. Even the Web Dispatcher would not respond, but emails generated had the
> proper links and HTTP references.
> 
> 2.	Creating an entry in HTTPURLLOC table; this seems to generate proper
> URLs by testing class CL_SWN_URL_GENERATOR, but actual message generation
> through SWN_SELSEN still uses the fully qualified name of the initiating
> instance. This is kept though, as CL_SWN_URL_GENERATOR is used by other parts of
> my workflows to send information messages.
> 
> 3.	Setting WG_HOST; in transaction SWNCONFIG -> General Settings ->
> WG_HOST is set as <http://sapwebdisp:8100/sap/bc/gui/sap/its/webgui/>. This gives
> me correct links in the body of the emails generated, so I have an
> operating solution. The problem here is that HTML formatting is lost, due to the
> fact that the message source still contains references to the fully
> qualified name of the server, e.g.  <html><head><title></title><base href="
> sapp1.company.com "…>.
> 
> Maybe you have an alternative solution to propose? It seems that the only
> problem remaining with my solution (points 2 and 3) is the reference of the
> fully qualified name in the message source; can that be altered somehow
> with customizing or parameter settings?
