Hi Nikhil Jain
Check table t056a in SE11
From should be greater value and to should be lower value then only will get data from database.
Try like this
TYPES : BEGIN OF ty_t056a,
vzskz TYPE t056a-vzskz,
datab TYPE char10,
referenz TYPE t056a-referenz,
END OF ty_t056a.
DATA : output_low TYPE sy-datum,
output_high TYPE sy-datum,
it_t056a TYPE TABLE OF ty_t056a,
wa_t056a TYPE ty_t056a.
DATA: s_low(10) TYPE C,
s_high(10) TYPE C.
SELECT-OPTIONS : s_datab FOR sy-datum.
CALL 'DATE_CONV_INT_TO_EXT'
ID 'DATINT' FIELD s_datab-low
ID 'DATEXT' FIELD s_low.
CALL 'DATE_CONV_INT_TO_EXT'
ID 'DATINT' FIELD s_datab-high
ID 'DATEXT' FIELD s_high.
CALL FUNCTION 'CONVERSION_EXIT_INVDT_INPUT'
EXPORTING
input = s_low
IMPORTING
output = output_low.
CALL FUNCTION 'CONVERSION_EXIT_INVDT_INPUT'
EXPORTING
input = s_high
IMPORTING
output = output_high.
SELECT vzskz
datab
referenz
FROM t056a INTO TABLE it_t056a WHERE datab BETWEEN output_high AND output_low.
Loop at it_t056a into wa_t056a.
CALL FUNCTION 'CONVERSION_EXIT_INVDT_OUTPUT'
EXPORTING
input = wa_t056a-datab
IMPORTING
OUTPUT = wa_t056a-datab.
modify it_t056a from wa_t056a TRANSPORTING datab.
clear wa_t056a .
endloop.
Loop at it_t056a into wa_t056a.
Write: / wa_t056a-vzskz, wa_t056a-datab, wa_t056a-referenz.
endloop.
