Hi,

Authorization Checks

For authorization checks, there are many ways of linking authorization objects with user actions in an R/3 system. The following discusses three possibilities in the context of ABAP programming.

Authorization Check for Transactions

You can directly link authorization objects with transaction codes. You can enter values for the fields of an authorization object in the transaction maintenance. Before the transaction is executed, the system compares these values with the values in the user master record and only starts the transaction if the appropriate authorization exists.

Authorization Check for ABAP Programs

For ABAP programs, the two objects S_DEVELOP (program development and program execution) and S_PROGRAM (program maintenance) exist. They contains a field P_GROUP that is connected with the program attribute authorization group. Thus, you can assign users program-specific authorizations for individual ABAP programs.

Authorization Check in ABAP Programs

A more sophisticated, user-programmed authorization check is possible using the Authority-Check statement. It allows you to check the entries in the user master record for specific authorization objects against any other values. Therefore, if a transaction or program is not sufficiently protected or not every user that is authorized to use the program can also execute all the actions, this statement must be used.

AUTHORITY-CHECK OBJECT 0.

MESSAGE e184(sabapdocu) WITH text-010.

ENDIF.

START-OF-SELECTION.

SELECT carrid connid fldate seatsmax seatsocc

FROM sflight

INTO CORRESPONDING FIELDS OF wa_flights

WHERE carrid = pa_carr.

WRITE: / wa_flights-carrid,

wa_flights-connid,

wa_flights-fldate,

wa_flights-seatsmax,

wa_flights-seatsocc.

ENDSELECT.

In this example, the system checks with the authorization object S_CARRID whether or not the user has a display authorization (03) for the airline entered on a selection screen. If this is not the case, or a different error occurs, the Selection Screen Processing goes back to the display of the selection screen

Hi,

Also check this

general different users will be given different authorizations based on their role in the orgn.

We create ROLES and assign the Authorization and TCODES for that role, so only that user can have access to those T Codes.

USe SUIM and SU21 T codes for this.

Much of the data in an R/3 system has to be protected so that unauthorized users cannot access it. Therefore the appropriate authorization is required before a user can carry out certain actions in the system. When you log on to the R/3 system, the system checks in the user master record to see which transactions you are authorized to use. An authorization check is implemented for every sensitive transaction.

If you wish to protect a transaction that you have programmed yourself, then you must implement an authorization check.

This means you have to allocate an authorization object in the definition of the transaction.

For example:

program an AUTHORITY-CHECK.

AUTHORITY-CHECK OBJECT <authorization object>

ID <authority field 1> FIELD <field value 1>.

ID <authority field 2> FIELD <field value 2>.

...

ID <authority-field n> FIELD <field value n>.

The OBJECT parameter specifies the authorization object.

The ID parameter specifies an authorization field (in the authorization object).

The FIELD parameter specifies a value for the authorization field.

The authorization object and its fields have to be suitable for the transaction. In most cases you will be able to use the existing authorization objects to protect your data. But new developments may require that you define new authorization objects and fields.

http://help.sap.com/saphelp_nw04s/helpdata/en/52/67167f439b11d1896f0000e8322d00/content.htm

To ensure that a user has the appropriate authorizations when he or she performs an action, users are subject to authorization checks.

Authorization : An authorization enables you to perform a particular activity in the SAP System, based on a set of authorization object field values.

You program the authorization check using the ABAP statement AUTHORITY-CHECK.

AUTHORITY-CHECK OBJECT 'S_TRVL_BKS'

ID 'ACTVT' FIELD '02'

ID 'CUSTTYPE' FIELD 'B'.

IF SY-SUBRC 0.

MESSAGE E...

ENDIF.

'S_TRVL_BKS' is a auth. object

ID 'ACTVT' FIELD '02' in place 2 you can put 1,2, 3 for change create or display.

The AUTHORITY-CHECK checks whether a user has the appropriate authorization to execute a particular activity.

This Authorization concept is somewhat linked with BASIS people.

As a developer you may not have access to access to SU21 Transaction where you have to define, authorizations, Objects and for nthat object you assign fields and values. Another Tcode is PFCG where you can assign these authrization objects and TCodes for a profile and that profile in turn attached to a particular user.

Take the help of the basis Guy and create and use.
