One of the biggest values for any company is its Intellectual Property and SAP is trying to protect its Knowledge. As a result, most of the SAP Knowledge Base Articles are protected (gated). Only Users with S-user credentials have access to most of the SAP Knowledge Base.
But Crystal Reports is a separate case. It is a Client application that does not require a maintenance agreement, so a S-user ID is not provided to the owners of the application.
As an exception, SAP provided public access to all Crystal Reports related Knowledge Base articles.
Here is an example of the KBA link:
https://apps.support.sap.com/sap/support/knowledge/public/en/1638102
The last digits are the actual KBA number. If a user knows the KBA number then just add it at the end of:
https://apps.support.sap.com/sap/support/knowledge/public/en/
So far Google is the best Search engine for Crystal Reports Public KBAs. But sometimes Google search returns Gated links. Use the last digits and the above link to get access to the KBA you need.
If you come across any Crystal Reports related KBA without Public access, just comment on this blog and we will do our best to make sure it is accessible.
