Select-option on subscreen for Module pool

Question

Hi all,
I need to add some elements on standard screen of a standard transaction. Everything works fine, but the problem starts when I want to add select-option. It is displayed, but when I press on Multiple selection button no action occurs, no window appears...I simplified the case and created test program with test screen and also I get the same behaviour. Anyone had similiar problem?
Thnak you in advance for help,
Anna

Answer 1

I donot know how u have created the select-option. but u can try these 2 methods to create it. And I have checked that both of them work fine.
1) How to create a select-options in a module pool screen.
Method 1
a) Create a subscreen area in your screen layout where you want to create the select options.
b) In the top include of  your module pool program declare a selection screen as a subscreen e.g.
       SELECTION-SCREEN BEGIN OF SCREEN 100 AS SUBSCREEN.
             select-options s_matnr for mara-matnr.
       SELECTION-SCREEN END OF SCREEN.
c) In the PBO and PAI of the main screen where the select options needs to be created do a call subscreen of the above screen (100).
       CALL SUBCREEN sub_area INCLUDING  <program>   <screen>
  This call subscreen statement is necessary for transport of values between screen and program.
Note: All validations of the selection screen fields e.g. the s_matnr field created above should be done in selection screen events like AT SELECTION-SCREEN etc and not in PAI. These selection screen validations etc should be done in the top include only.
Method 2
a) Create 2 separate fields in your screen layout - one for the low value and one for the high value. Insert an icon beside the high value which will call the multiple selections popup screen on user command. Use function module COMPLEX_SELECTIONS_DIALOG to achieve this.
struc_tab_and_field-fieldname = con_cust.  " 'KUNNR'
struc_tab_and_field-tablename = con_kna1.  " 'KNA1'.
CALL FUNCTION 'COMPLEX_SELECTIONS_DIALOG'
          EXPORTING
          TITLE                   = ' '
            text                         = g_titl1                                " 'Customers'
            tab_and_field     = struc_tab_and_field
          TABLES
            RANGE                   = rng_kunnr
          EXCEPTIONS
            NO_RANGE_TAB          = 1
            CANCELLED                    = 2
            INTERNAL_ERROR     = 3
            INVALID_FIELDNAME = 4
            OTHERS                           = 5.
IF NOT rng_kunnr[] IS INITIAL.
         Read the very first entry of the range table and pass it to
         dynpro screen field
           READ TABLE rng_kunnr INDEX 1.
           IF sy-subrc = 0.
              g_cust = rng_kunnr-low.
ENDIF.
You can use the return table rng_kunnr to populate your own internal range table with the values entered by the user. Basically here you are just simulating the work of a select-options parameter by module pool screen elements.
