As per SAP Note 2077230

we need do workaround to avoid this error after upgrade of SAP GUI.

In your windows workstation; go to location of “SAPUILandscape.xml”.

use RUN (open RUN using combination of WindowsKey+R) and type “%appdata%”

you can find the SAPUILandscape.xml inside SAP folder.

Edit this file (SAPUILandscape.xml) using Notepad or Notepad++ (optional, widows application).

you need to Scroll it to down and find the entries related to “<Routers>” & change the entries as per SAP Note.

you should replace or change  /H/” to ” followed by re-start of SAP GUI (close all sessions and re-open SAP GUI).

 

i.e….when opened in notepad, you need to change the following:

Note: Here 10.20.30.40 as an example for router String.

router=”/H/10.20.30.40/H/”/>

to

router=”/H/10.20.30.40″/>

 

router=”/H/server.company.com/H/”/>

to

router=”/H/server.company.com”/>

Change the Router.jpg

To make it simple:-

1 – windowsKey+R.

2 – Type ” %appdata%\SAP ” (type without ” ).

3 – Backup the Original files to another location.

4 – Open SAPUILandscape.xml file with notepad.
5 – Use Key board short cut, ctrl+H for find and replace.
5.1 – Key in the string in Find ” router=”/H/<IPaddress of SAP router / FQDN of SAP router>/H/”/> “.
5.2 – Key in the string in replace  ” router=”/H/<IPaddress of SAP router / FQDN of SAP router>“/> “.

6 – Save changes.
7 – Close all SAP GUI sessions (save and logoff, just in case).

8 – close SAP GUI
9 – Re-open SAP GUI & you can try connecting to SAP server.

 

Normal SAP GUI entry will be as below:-

After Editing the .xml file and restart of SAP GUI, the entry looks like as below:-

For your information only:-

The .Xml file contains the following parts, easy to understand when opened with IE. But, edit using notepad or notepad++.

Note: the number of entries is dependent on number of entries maintained by you in SAP GUI.

      It works for me.

      I've spent several hours to install and uninstall some different SAP GUI versions until I found this post.

      Thanks.
