hi
chk this out
AUTHORITY-CHECK
Basic form
AUTHORITY-CHECK OBJECT object
    ID name1  FIELD f1
    ID name2  FIELD f2
    ID name10 FIELD f10.
Effect
Explanation of IDs:
object
Field which contains the name of the object for which the authorization is to be checked.
name1 ...
Fields which contain the names of the
name10
authorization fields defined in the object.
f1 ...
Fields which contain the values for which the
f10
authorization is to be checked.
AUTHORITY-CHECK checks for one object whether the user has an authorization that contains all values of f (see SAP authorization concept).
You must specify all authorizations for an object and a also a value for each ID (or DUMMY).
The system checks the values for the IDs by AND-ing them together, i.e. all values must be part of an authorization assigned to the user.
If a user has several authorizations for an object, the values are OR-ed together. This means that if the CHECK finds all the specified values in one authorization, the user can proceed. Only if none of the authorizations for a user contains all the required values is the user rejected.
If the return code value in SY-SUBRC is 0, the user has the required authorization and may continue.
The return code value changes according to the different error scenarios. The return code values have the following meaning:
4
User has no authorization in the SAP System for such an action. If necessary, change the user master record.
8
Too many parameters (fields, values). Maximum allowed is 10.
12
Specified object not maintained in the user master record.
16
No profile entered in the user master record.
24
The field names of the check call do not match those of an authorization. Either the authorization or the call is incorrect.
28
Incorrect structure for user master record.
32
Incorrect structure for user master record.
36
Incorrect structure for user master record.
If the return code value is 8 or 24, inform the person responsible for the program. If the return code value is 4, 12, 16 or 24, consult your system administrator if you think you should have the relevant authorization. In the case of errors 28 to 36, contact SAP because authorizations have probably been destroyed.
Individual authorizations are assigned to users in their respective user profiles, i.e. they are grouped together in profiles which are stored in the user master record.
Note
Instead of ID name FIELD f, you can also write ID name DUMMY. This means that no check is performed for the field concerned.
The check can only be performed on CHAR fields. All other field types result in 'unauthorized'.
Example
Check whether the user is authorized for a particular plant. In this case, the following authorization object applies:
Table OBJ: Definition of authorization object
M_EINF_WRK
   ACTVT
   WERKS
Here, M_EINF_WRK is the object name, whilst ACTVT and WERKS are authorization fields. For example, a user with the authorizations
M_EINF_WRK_BERECH1
   ACTVT 01-03
   WERKS 0001-0003 .
can display and change plants within the Purchasing and Materials Management areas.
Such a user would thus pass the checks
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
    ID 'WERKS' FIELD '0002'
    ID 'ACTVT' FIELD '02'.
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
    ID 'WERKS' DUMMY
    ID 'ACTVT' FIELD '01':
but would fail the check
AUTHORITY-CHECK OBJECT 'M_EINF_WRK'
    ID 'WERKS' FIELD '0005'
    ID 'ACTVT' FIELD '04'.
To suppress unnecessary authorization checks or to carry out checks before the user has entered all the values, use DUMMY - as in this example. You can confirm the authorization later with another AUTHORITY-CHECK
