Selection screen and authorization check for plant from 2 diff tables?

Question

Hi,
Could anyone help me out?
how to write code for  this?
u2022   Fields for selection
Plant : WERKS (one selection) - check authorization access u2013 Mandatory .
Material code MATNR (one selection) - Mandatory
and while doing the authorization check how should i check it ? here iam taking the table as t001w for werks and for selection screen iam taking it from another Z table......i should take 2 different tables here.....for selection and for authorization.
my code is pasted below:
                 Data Declarations                                  *
data: s_werks type t001w-werks.
                 Selection Screen                                    *
  SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-h01.
  PARAMETER : p_werks like Ztable-werks OBLIGATORY,
              p_matnr like mara-matnr  OBLIGATORY.
  SELECTION-SCREEN END OF BLOCK b1.
                 Start-of-Selection                                  *
START-OF-SELECTION.
**-Get Plants for Authorization check.
   SELECT werks
          FROM t001w
          INTO TABLE it_werks
      WHERE werks IN s_werks.
    LOOP AT it_werks INTO x_werks.
       v_werks = x_werks.

Plant : WERKS (one selection)
That means only 1 plant value to be given? Then you can use PARAMETERS instead of SELECT-OPTIONS. And additionally, you'll only have to check that plant value.
Using SELECT-OPTIONS you would indeed retrieve the plants and check each individual selected plant. Your code for that is good enough to start with.
I wouldn't do the check in the START-OF-SELECTION event, but rather in the AT SELECTION_SCREEN event.
To perform an authorisation check; try the ABAP help on AUTHORITY-CHECK. And you will need to know which authorisation object you need to use.
Just noticed you're using PARAMETERS
WHERE werks IN s_werks
should be
WHERE werks eq p_werks
But actually you don't need to select T001W. Just use the value in p_werks.
