KB0002 – WAS logon configuration

NOTE : The information in this Knowledge Base entry is designed to apply the SAP standard configuration procedure to Promenta’s solution. It is not meant as a comprehensive guide and you should refer to SAP’s own documentation where appropriate. Promenta is not responsible for the content of external links.


You use Promenta Webflow with the WAS rendering engine. You wish to configure form-based logon instead of the default basic authentication (browser popup)

To complete this configuration you should be familiar with the concept of the External Service Alias. See this link for more information : https://help.sap.com/doc/saphelp_nwpi71/7.1/en-US/78/9852bdc06b11d4ad310000e83539c3/content.htm?no_cache=true


The Webflow solution is delivered with default authentication but this can be overridden without an ABAP repair using the external alias functionality. This is carried out in every system (dev, QA , Production)


1) Ensure SICF is configured for logon – activate all services under:

2) Override Promenta WAS renderer using an external alias with the same path


3) Configure the external alias for form logon
Open the external alias
Go to tab Error Pages
Go to sub-tab Logon Errors
Select System Logon
Configure the System logon as shown below:

Alias  : /sap/bc/bsp/promenta/wfbsp

Service (triggering Element) : /default_host/sap/bc/bsp/promenta/wfbsp

Then choose Error Pages tab –> Choose “System logon” radio button and click “Configuration” button

End result is shown below

4) Test logon by accessing a Promenta solution in the normal way eg from the Workbench –> Test option or use transaction /n/PROMENTA/DASHBOARD2

Ensure you receive no popup logon boxes – only a form logon as shown below (note your styling may be different)
