Pass uname into RFC FM


In my OrgChart (3.0 SP2, SSO with Logon tickets) data retrieves from SAP under system user. Now I need to pass real user name into z-FM (to restrict some data retrieving), but call this FM under system user. Is that possible, to pass user name as input parameter? How?

Best regards,

Sergey Aksenov

    Good question 😊

    I haven't tried this recently but previously you could reference fields in the user object (see data element UserPopulationInfo for the fields available).

    Format to reference the field was:


    So you should be able to use this in your NakisaRFC config (OTFSchema) for example to pick up the user id of the current user and use it to drive the data extraction.

    If the above format doesn't work, try


    Does that help?

    Hi Sergey,

    In your function module you need to declare SY-UNAME so that it uses the logged-in users user Id.

    Best regards,
