The SAP Library navigation structure reflects the complete SAP product portfolio. Each node within the structure represents a single SAP solution or product.

However, you may not have licensed and installed all SAP products and the corresponding SAP Library documentation. So when you click on a node and the documentation for the solution or product is not displayed, this is not an error. It is because the SAP Library installed on your server reflects only those products and business functions that you have licensed, installed, and activated. As soon as you license, install, and activate additional products or business functions with their product documentation, the SAP Library will be automatically extended to include this.
