KB0019 – Hub portal setup
If an SAP portal is involved in a customer landscape it can be used to provide services such as Single-Sign-on and additional security
Promenta supports the following scenarios :
1) Portal 1-to-1 with ECC system.
Each ECC system has its own portal – this is the default install and is documented in the standard setup guide
2) Portal 1-to-many ECC systems [Hub install]
A single portal provides access to multiple ECC systems
This Knowledge Article explains the configuration for scenario 2 – Hub install.
Hub install
The diagram below shows a typical landscape with 4 ECC systems connected to one portal.

Configuration – Portal
In the Portal each ECC systems requires a unique Alias
The Alias should point to the ECC system and the ECC system connection should be set up as a Web Application Server connection
The connection must be tested and working
Note : The Alias will need to be the same on all portals in the landscape (ie same on development, QA and production)
Configuration- ECC
1) Use Transaction SM30 in Development system
2) Table /PROMENTA/TM999
3) Enter the alias for this ECC system in WEBFORMS / PORTAL_SAPALIAS

4) Save in a transport and migrate through the landscape in the normal way
Testing
To confirm the Alias is working correctly:
1) Open workbench and execute example form /PROMENTA/EXMPL_2 as described here
2) Check the generated URL – it should contain new parameter as per example below
