SUSR_CHECK_LOGON_DATA return code 3

kmoore007 — Thu, 27 Aug 2009 19:59:04 GMT

I am trying to test function module SUSR_CHECK_LOGON_DATA, but keep getting an error message 'USER_OR_PASSWORD_INCORRECT'. If I debug the function, the error is occuring at a system function

CALL 'INTERNET_USER_LOGON' which returns sy-subrc = 3.

The parameters I am passing look like this:

Import parameters Value

AUTH_METHOD E

USERID KLM1

ALIASNAME

PASSWORD

AUTH_DATA CHPF\klm1

EXTID_TYPE NT

LANGUAGE

USE_NEW_EXCEPTION 0

Any ideas?

Are you trying to migrate SU05 users to SU01 users, or have you misinterpreted the purpose of this FM?

Perhaps what you are looking for is SUSR_FORMAL_PASSWORD_CHECK or SUSR_USER_PASSWORD_STATUS_GET?

What is the purpose for calling this FM?

Cheers,

Julius

I was following this BLOG [Single Sign On with External ID implemented in Ruby|https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/4587] [original link is broken] [original link is broken] [original link is broken];. I had setup table view VUSREXTID and was trying to test the function module to see how it works. I want to generate an SAP Logon Ticket, that's my goal.

If you test-drive an ABAP function module using transaction SE37 kindly notice that you might need to set the option "Uppercase/Lowercase" [X]. By default, all lower-case characters entered on the screen will be converted to upper-case characters before passing the parameters to the function module.

In case of SUSR_CHECK_LOGON_DATA that might be critical (if your system is of release 7.x).

Please notice in addition:

SUSR_CHECK_LOGON_DATA will only return a SAP Logon Ticket if called via SNC-protected RFC (from outside) if being called with AUTH_METHOD = 'E' or 'X' (reason: otherwise SNCSYSACL cannot be evaluated). So, you cannot test-drive this locally (via SE37).
