Managing SAP user data with Identity GUID via an ABAP Class

Purpose

BAPIs or SAP standard functions for USR are pretty handy in managing SAP user data in most cases but how about if an external system needs a USER GUID instead of BNAME to search SAP user ? What if a case of that you need to manage SAP user data only by GUID (Identity)?       

Class CL_IDENTITY_FACTORY is providing very useful functions for user & for user Identity such as searching, deleting, creating, checking, and more. Even the use of CL_IDENTITY_FACTORY is not complicated as it has only static & public methods which giving you direct access without instantiating an object .

Example

If you want to check SAP user existence in SAP system, Checking USR table might be the simplest way. However, here is an other way to do that

DATA : LV_BNAME                     TYPE          XUBNAME,

LS_MESSAGE                TYPE          SYMSG,

LS_BNAME_EXIST        TYPE          SUID_ST_IDENTITY.

* Check User existance

LV_BNAME  = CV_USERNAME.

CL_IDENTITY_FACTORY=>EXISTENCE_CHECK(

EXPORTING

IV_BNAME                = LV_BNAME

IMPORTING

ES_IDENTITY           = LS_BNAME_EXIST  ).

**

*  IF LS_BNAME_EXIST IS INITIAL.

*    RAISE EXCEPTION

**********************

*    RETURN.

*  ELSE.

*  ENDIF.

IS_BNAME_EXIST  = LS_BNAME_EXIST.

Extra

You can  also send a query for user data or deal with multiple users or get info of BPs assigned to the users. To get further & deeper handling, check out class CL_IDENTITY  .
