Reading Selection Screen Values

Former Member — Thu, 17 Oct 2013 09:19:17 GMT

Hi Gurus,

I have a requirement of restricting the data based on some selection screen parameters. I have these parameters on Report WS_MONITOR_OUTB_DEL_FREE.

Now this report calls the Function module WS_DELIVERY_MONITOR which performs the processing. This Function module does not have the selection parameters which I have added. So I tried to get my added parameters using FM RS_LIST_SELECTION_TABLE, but this FM is not working.

Reason being sy-repid is not having the program value. So I am passing the program value manually i.e. WS_MONITOR_OUTB_DEL_FREE, but not found anything.

Please give me your valuable suggestions on this.

Thanks in advance,

Sumit

Hi,

You can enhance the function module to add the selection parameters in its interface and change the logic as required.

PS:While changing interface always mark the added parameters as OPTIONAL.

Thanks Ashish!!!

This is the last option I would do, changing the interface of FM. Is there any other way to read those Selection screen parameters in that FM????

Please suggest.

what about DYNP_VALUES_READ

Yes, from your selection screen you can pass the values to ABAP memory using EXPORT TO MEMORY statement and read it back in FM using IMPORT TO MEMORY.

Another way is to set parameter IDs for the fields and pass the value to SAP Memory and read it back in the FM.

Or you can use FM DYNP_VALUES_READ as mentioned by Nabheet madan.

In any case, to process those additional fields you will have to enhance the logic of the FM.

Hi,

Use the below link,

Or you can try my code.

REPORT XXXXXXXX.
Tables : tvko.
Data : int_vkorg TYPE TABLE OF tvko-vkorg.
PARAMETERS : p_bukrs TYPE tvko-bukrs,
                           p_vkorg TYPE tvko-vkorg.

        x_ft TYPE dfies,

        x_dd TYPE dselc,
        t_tvko TYPE TABLE OF tvko,
        x_tvko TYPE tvko.

       ls_dynfld TYPE dynpread.

APPEND ls_dynfld to lt_dynfld.

Refresh t_ft.
x_ft-tabname = 'TVKO'.
x_ft-fieldname = 'BUKRS'.
APPEND x_ft To t_ft.

REFRESH t_ft.

START-OF-SELECTION .
SELECT * from tvko INTO TABLE t_tvko WHERE bukrs = p_bukrs and vkorg = p_vkorg.
If sy-subrc eq 0.
    WRITE : 'Success' .
ENDIF.

Hope this helps.

Hi,

DYNP_VALUES_READ can only read the values that are visible on the screen i.e. if I amusing SELECT-OPTIONS with intervals then values entered in multiple selection will not be made available using this FM.

Thanks guys for all your suggestion. I have used Global stack to acheive the solution.

Cheers,

Sumit
