Was verursacht dieses Problem?

You use the extended notifications for SAP Business Workflow to inform
users about new work items.
You send the notifications by e-mail. The e-mails contain links with the
following text and empty URLs:
<(><<)>Action>: Invalid link (SWN155)
<(><<)>Action> is a placeholder for the actions display work item,
execute work item, or call workflow inbox.
In the subscription (transaction SWNCONFIG or SWNADMIN) you define which
front-end application is to be used to display or execute the work items
and SAP Workflow inbox.
The configuration (task visualization) from transaction SWFVISU is also
applied. If a visualization type (for example, WebDynpro Java) is
configured for the relevant single-step tasks, this setting overrides
the setting from the subscription.
HTTP links or executable attachments are generated in the e-mail to
enable you to start the selected front-end application from within the
e-mail.
If generation is not possible because the configuration is incomplete,
an HTTP link with the text
'<(><<)>Action>: Invalid Link (SWN155)' and an empty URL are generated
instead.

Systemantwort

Wie behebe ich diesen Fehler?

Check the settings in the subscription on the basis of which the
notification was sent.
Check the settings in transaction SWFVISU for the single-step task on
which the work item is based.
Check in the general settings in transaction SWNCONFIG or SWNADMIN
whether the parameters WD_HOST and WG_HOST are set accordingly.
