Hi Experts,

Am learning abap, could someone please explain the following code;

IF i_step EQ 0 OR " without popup

i_step EQ 1 OR " before popup

i_step EQ 2. " after popup

REFRESH e_t_range.

CLEAR: l_s_range.

CLEAR : s1, s2.

DATA v_pm(6) TYPE c.

s1 = sy-datum.

s2 = sy-datum.

*Date must be in YYYYMM format

IF i_vnam = 'ZUEPOSTM' AND s1+6(2) = '01'.

s1 = s1 - 1.

s1+6(2) = '01'.

s1 = s1 - 1.

v_pm(4) = s1+0(4).

v_pm4(2) = s14(2).

ELSE.

s1+6(2) = '01'.

s1 = s1 - 1.

v_pm(4) = s1+0(4).

v_pm4(2) = s14(2).

ENDIF.

l_s_range-sign = 'I'.

l_s_range-opt = 'EQ'.

l_s_range-low = v_pm.

APPEND l_s_range TO e_t_range.

ENDIF.

I appreciate your time with points,

Thanks

Hi,

Hi,

Check the documentation..

If the I_STEP is equal to 0 or 1 or 2..Then the do the following..

IF i_step EQ 0 OR " without popup

i_step EQ 1 OR " before popup

i_step EQ 2. " after popup

REFRESH e_t_range.

CLEAR: l_s_range.

CLEAR : s1, s2.

DATA v_pm(6) TYPE c.

Store the current date in the variables S1 and S2.

s1 = sy-datum.

s2 = sy-datum.

If the i_vnam = 'ZUEPOSTM' and if it is start of the month..Means 01

*Date must be in YYYYMM format

IF i_vnam = 'ZUEPOSTM' AND s1+6(2) = '01'.

Decrement the date by 1 day...Means if 01 - feb - 2006 then it will be 01 - Jan - 2006

current date = 12/26/2006

s1 = s1 - 1. "s1 = 20061225

s1+6(2) = '01'. "s1 = 20061201

s1 = s1 - 1. "s1 = 20061130

v_pm(4) = s1+0(4). " v_pm = 2006

v_pm4(2) = s14(2). " v_pm = 200611

ELSE.

s1+6(2) = '01'. "s1 = 20061201

s1 = s1 - 1. "s1 = 20061130

v_pm(4) = s1+0(4). " v_pm = 2006

v_pm4(2) = s14(2). " v_pm = 200611

ENDIF.

l_s_range-sign = 'I'.

l_s_range-opt = 'EQ'.

l_s_range-low = v_pm.

APPEND l_s_range TO e_t_range.

ENDIF.

Basically it is getting the previous month and year..Build a range with it..

Thanks,

Naren

Naren,

Thanks a ton for your time, also could you please tell me what the following will

do;

l_s_range-sign = 'I'.

l_s_range-opt = 'EQ'.

l_s_range-low = v_pm.

APPEND l_s_range TO e_t_range.

Full points to u.

Hi,

This will build a range internal table..

l_s_range-sign = 'I'.

l_s_range-opt = 'EQ'.

l_s_range-low = v_pm.

APPEND l_s_range TO e_t_range.

Which means..You can check if the year and month is with in the range..You have to use IN operator to check the data..

The ranges are similar to select-options..Only think is the ranges will not be displayed in the selection-screen..

Example.

IF '200611' IN e_t_range.

True.

ELSE.

False.

ENDIF.

Thanks,

Naren
