Hi,

Try this..

DATA: V_INPUT(6) TYPE N VALUE '200401'.
DATA: V_OUTPUT(6) TYPE N.
DATA: V_DATE TYPE D.

CONCATENATE V_INPUT '01' TO V_DATE.

call function 'RE_ADD_MONTH_TO_DATE'
         exporting
              months  = '-1'
              olddate = v_date
         importing
              newdate = v_date.



V_OUTPUT = V_DATE(6).

WRITE: / V_OUTPUT.

Thanks,

data :v_date(6) type c.

data v_dat(2) type c.

data :v_mon(2) type c

start-of-selection.

v_dat = v_date+4(2).

case v_dat.

when '01'.

v_mon = '12'

when '02'

v_mon = '01'

when '03'

v_mon = '02'

when '04'

v_mon = '03'

when '05'

v_mon = '04'

when '06'

when '07'

when '08'

when '09'

when '10'

when '11'

when '12'

endcase.

use case statement and concatenate to one more varaible

if you are talking about periods maintained in table t009 you can use this fm:

ISB_PREVIOUS_PERIOD_GET

Hi,

There are a lot of function module for Date caculations, so U can go to SM37 to find out the appropriate function for your use.

Hope this helps

Hi Saritha,

Try this simple coding.

DATA datum(6).

DATA last_month(6).

datum = '200501'.

If datum+4(2) = '01'.

last_month0(4) = datum0(4) - 1.

last_month+4(2) = '12'.

else.

last_month = datum - 1.

endif.

WRITE / last_month.

Hi Saritha,

I'm not sure if there is a function module for this..

you can actually write the logic for this as follows:

data : date(6) value '200401'.
data : month(2), year(4).
data : final(6).
month = date+4(2).
year = date+0(4).
month = month - 1.
if month = 0.
  year = year - 1.
  month = 12.
endif.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    input         = month
 IMPORTING
   OUTPUT        = month
          .
concatenate year month into final.
write : final.

Hope this helps
