Hi Friend,

i thing this will help u.

For more information see the Release Information on customer

enhancements and the documentation for the function modules

EXIT_SAPFGRWX_001, EXIT_SAPFGRWS_001 and EXIT_SAPFGRWE_001.

Release Information

Short text

Report Writer: Customer Enhancements for Authorization Check

Scope of Functions

To meet customer requirements for individual authorization checks the

standard checks have been extended to include customer exits that can be

called at three different points in time:

o Check during extract output

This exit is called when an extract is output in the report output

or when within an extract you branch to a different report or to a

different node of the varied hierarchy.

o Check on single record level during data selection

This exit is called for each record read during data selection.

o Check on the initial screen

This exit is called on the selection screen for each report and each

section of the report group once.

These can be edited as part of the SAP enhancement management (menu

"Tools -> ABAP Workbench -> Utilities -> Enhancements -> Project

management"). For more information about SAP enhancement management,

from this transaction (CMOD) see the documentation available from the

menu under "Goto -> Online manual".

The function modules are combined under the SAP extension "GRWTAUTH". An

include program with example coding has been defined for each function

module. These examples give a hint as to how the transfer structures of

the individual functions are to be interpreted. They are, however,

neither complete nor are they optimized for runtime.

Function Module When Called Include Program

EXIT_SAPFGRWE_001 Extract output LXRWAF01

EXIT_SAPFGRWS_001 Selection LXRWAF02

EXIT_SAPFGRWX_001 Initial screen LXRWAF03

You can find more information on the subject of customer exit

programming in the documentation of the corresponding function module.

EXIT_SAPFGRWE_001

Customer exit: Authorization check for extract display

Functionality

This exit is always called up when an extract is outputted in the report

output or another report or node in the hierarchy is linked to within

the extractor.

A standard check is not carried out for all report writer tables.

Provided that the report writer table supports standard checks, these

will be performed in subprogram C02_CHECK_DATA_AUTHORITY in the form

pool assigned to the report writer table (T804A MPOOL).

If a standard check exists, the exit can use parameter

E_SKIP_STANDARD_EXIT to specify whether the standard check is then to be

performed or skipped. If the standard check is then performed, it

dictates authorization. If the exit triggers exception NO_AUTHORITY, the

standard check is always skipped with E_SKIP_STANDARD_EXIT = 'X' .

Table parameter I_T_SELECTIONS describes the general selection

conditions of the report or variation report in question, on the basis

of which authorizations can be checked. For each selection

characteristic, table I_T_SELECTIONS contains an entry that provides

information on the corresponding selection set or the selection value.

For varied characteristics, the corresponding specification for the

corresponding variation report is specified.

T804A MPOOL

Module pool for routines

Definition

Here you must enter a form pool that contains the ABAP routines that are

defined in the control tables.

EXIT_SAPFGRWS_001

Customer exit: Authorization check at single record level in

Functionality

This exit is called up for each individual data record during data

selection. When making a new selection it is called up from the database

(I_DATA_SOURCE = 'S'), while when reading it is called up from the

archive (I_DATA_SOURCE = 'A'). The current data record is passed on in

the untyped parameter I_S_RECORD to the exit, the corresponding DDIC

reference structure in parameter I_DB_TABLE.

A standard check is not carried out for all report writer tables.

Provided that the report writer table supports standard checks, these

will be performed in the subprogram (T804A AUTHR) in the form pool T804A

MPOOL) assigned to the report writer table.

If a standard check exists, the exit can use parameter

E_SKIP_STANDARD_EXIT to specify whether the standard check is then to be

performed or skipped. If the standard check is then performed, it

dictates authorization for the current data record. If the exit triggers

exception NO_AUTHORITY, the standard check is always skipped with

E_SKIP_STANDARD_EXIT = 'X' .

EXIT_SAPFGRWX_001

Customer exit: Authorization checks on initial screen

Functionality

This exit is called when the user has filled in the selection screen and

started the execution of the report group. The function module is called

up once for each section in a report of the report group. Each call of

the exit is numbered in the parameter I_INDEX beginning with 1. Certain

initializations can be made when I_INDEX = 1.

There is no standard check of the entries on the selection screen for

all Report Writer tables. The standard check, if the Report Writer table

supports it, is made in the subprogram RW_X_AT_SELECTION_SCREEN in the

form pool (T804A-MPOOL) assigned to the Report Writer table.

The exit must collect messages using the function module MESSAGE_STORE.

Execution of the report group is terminated as soon as an E (error) or A

(abort) message is has been collected. The collected messages are then

output, and the user can check the entries on the selection screen.

If no E or A messages were issued, execution of the report group is

continued. Depending on the data source selected on the selection

screen, additional authorization checks are made which also can be

supplemented with your own exits:

o When data is reselected from the database (I_DATA_SOURCE = "S") or

when archived data is read (I_DATA_SOURCE = "A"), authorization for

the records being read can be checked record by record with the exit

EXIT_SAPFGRWS_001.
