Creating select option to get wadat from likp to use in the query

Question

Hi People,
Urgent Help. I have to make a select-option in my selection screen for date to use the field wadat from likp. Now the after the following code what should I be doing:
Selection-Screen BEGIN OF BLOCK b with frame Title t1.
PARAMETERS:
SELECT-OPTIONS: p_date for likp-wadat.
SELECTION-SCREEN END OF BLOCK b.
INITIALIZATION.
AT SELECTION-SCREEN.
START-OF-SELECTION.
<b>SELECT avbeln alfdat awadat akunnr bwerks bspart INTO
CORRESPONDING FIELDS OF TABLE typ_tab FROM likp as a INNER JOIN lips as b on avbeln = bvbeln where wadat IN p_dat.</b>
On the selection screen there will be two boxes for the from -to date...How does it work? If I have to make it only for one date or for range of dates. Please help asap. I have to use this value in a report to pull out delivery document details from likp and lips through the query mentioned above.
Thanks in advance.

Hey Nishanth,
Thanks for the reply. I made the changes as suggested but when I am entering a date which does not exist in the table, the screen does nothing. Can you suggest something for that.
Here is my code:
tables: likp.
SELECTION-SCREEN BEGIN OF BLOCK b_0 WITH FRAME TITLE date.
SELECT-OPTIONS p_date FOR likp-wadat NO-EXTENSION.
PARAMETERS p_glAccNo(80) TYPE C.
SELECTION-SCREEN END OF BLOCK b_0.
DATA: BEGIN OF typ_likp occurs 0,
                 vbeln LIKE likp-vbeln, " Bill Of Lading Number
                 lfdat LIKE likp-lfdat,
                 wadat LIKE likp-wadat,
      END OF typ_likp.
AT SELECTION-SCREEN ON p_date.
if p_date[] is NOT INITIAL.
SELECT vbeln wadat INTO TABLE typ_likp FROM LIKP WHERE wadat IN p_date.
IF sy-subrc <> 0.
WRITE: / 'No Values for this date.'.
Exit.
ENDIF.
ELSE.
WRITE: 'NO ENTRIES HAVE BEEN MADE'.
ENDIF.
START-OF-SELECTION.
SELECT vbeln lfdat wadat INTO TABLE typ_likp fROM LIKP where
wadat in p_date.
LOOP AT typ_likp.
Write: / typ_likp-vbeln, typ_likp-lfdat, typ_likp-wadat,
       / 'I am here.'.
ENDLOOP.
Please reply soon. I need to finish this at the earliest.
Thanks for your help, regards,
AM
