Step-by-step guide

One-time configuration - Assigning a service user in the following services:
/sap/bc/bsp/iqx/fab_srv
/sap/iqx/fab2_srv
/sap/iqx/fab_srv
/sap/iqx/services_srv
Use tcode SICF and provide the Service Path listed above. Click on

Double click on the node

Click on and provide the service user in the Logon Data tab
For each app that needs anonymous access, ensure that the Anonymous Access flag is selected. This will create the App's url having fab_srv instead of the usual fab_bsp.

Passing a value in the URL parameter "email=X@X.COM" will result in having the "SubmittedByEmail" system field be set to this email. In this way the email address can be bound to the form automatically.
