SAP NetWeaver Portal enables the creation of iViews based on remotely located systems. In case of connection failure, an exception will be raised. This blog was written in order to assist with troubleshooting the root cause of the connection failure.
In addition the following documentation page provides full description about this feature:
http://help.sap.com/saphelp_nw73ehp1/helpdata/en/f5/b36fcd92a5472bbad125a9c6a0fcf8/content.htm
and recently new traces have been added (see note number 1940155).
Background
While creating new content using the "content admin" role, you can choose to create "iView From Remote Source"
There are 4 different types of iViews from remote source available:
- SAP Portal Component iView - iView is based on a remote portal component
- Transaction - iView is based on a transaction from SAP back end system
- Web Dynpro ABAP - iView is based on content from SAP Web Dynpro ABAP from remote system
- Web Dynpro Java - iView is based on content from SAP Web Dynpro JAVA from remote system
The values filled in the wizard fields must be valid according to the type of remote iView being generated.
Prerequisites
Before using the iView from remote source feature the following Prerequisite must be filled:
- The relevant system must be defined under portal system landscape. Click here for more information about 'system landscapes'.
- Make sure to create alias to the relevant system. Click here for more information about 'Managing System Aliases'.
- Use the test connection feature while creating the system: Check the "Run connection test after clicking next". (make sure you type valid user and password)
The connection test should pass successfully
