This document is intended to help you solving problems that arise after upgrading your Enterprise Portal to 7.3x / 7.4 / 7.5 release.

1. Logon Page not rendered properly


After upgrading to NetWeaver 7.3X, 7.4 or 7.5 from older releases (like 7.0X) the custom logon screen no longer works, or you are facing issues to logon to your NetWeaver Administration (NWA) or Enterprise Portal.

The issue occurs most of the times due to the change in the logon screen mechanism comparing to earlier versions. In order to solve the issue, refer to SAP KBA 1935486 – NetWeaver Portal 7.3X/7.4 and custom logon screens

If you suspect that customizations made to the standard authschemes.xml, and you have been requested by SAP to revert your custom authschemes.xml file back to the Standard file provided by SAP,

refer to SAP KBA 1936725 – How to revert to standard authschemes.xml in NW 7.3X onwards

2. Browser Support / Chrome


After upgrading you cannot open iViews in Chrome browser.
Instead of the iView content, there is an error message:

“Could not open iView. The iView is not compatible with your browser, operating system, or device. Contact your system administrator for more  information.”
In order to solve the issue, refer to SAP KBA:
2266579 – Could not open iView in Chrome on launching portal

3. ICM session Time Out


You are facing short time out on the 7.30 migrated system .The default ICM session time out is set to 60 seconds.
