At selection screen validation doubt

Former Member — Wed, 23 Nov 2005 07:41:58 GMT

i hav At selection screen like this:-

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_path.

TABLES : tfdir.

DATA : prg_name LIKE sy-repid,

dynp_numb LIKE sy-dynnr,

field_name LIKE dynpread-fieldname.

SELECT SINGLE * FROM tfdir WHERE funcname = 'F4_FILENAME'.

IF sy-subrc EQ 0.

prg_name = sy-repid.

dynp_numb = sy-dynnr.

field_name = 'p_path'.

CALL FUNCTION 'F4_FILENAME'

EXPORTING

program_name = prg_name

dynpro_number = dynp_numb

field_name = field_name

IMPORTING

file_name = p_path.

ENDIF.

IF sy-subrc NE 0.

MESSAGE i000(zmsg).

ENDIF.

This fm is getting file name.

But I need only files with format " *.CSV " in this criteria.

How should I do this?

this code is also accepting anyother format other than " CSV ".

It should not allow if any other format is taken in the selection-screen.

It should only accept CSV format in sel. screen.

moreover..This field is a parameter not select-options.

My sel. screen is:-

parameters : p_path LIKE ibipparms-path.

One more thing..It should accept the file from the presentation server.

Hi Hari,

Once you read the file using F4_Filename, use function module SPLIT_FILENAME to check whether the file extension is CSV.

Thanks

HiHari,

Instead of f4_filename, use F4_DXFILENAME_4_DYNP where there is an option of specifying the filetype.

Hope this would solve your problem.

Allot points for valuable answers.

Warm Regards,

Vinod.
