function to a month

[Former Member]

hi,

I have the following code.

DATA: FECHA LIKE SY-DATUM(6),

FECHA1 LIKE SY-DATUM.

fecha1 = sy-datum.

fecha = FECHA1(6) - 1.

The result is 200700.

This result not exist like year.month, this result is not the expected for me. What i need is 200612.

There are some functions or some idea to obtain what I need?

I would appreciate your help.

Regards,

Victoria

CX_SY_CONVERSION_NO_NUMBER

Use this FM...

RP_CALC_DATE_IN_INTERVAL

You can ADD or SUBTRACT days, months or years -;)

just check this..

DATA: FECHA like sy-datum(6),
FECHA1 LIKE SY-DATUM.
data: mon(2) type c,
      year(4) type c.

fecha1 = sy-datum.
mon = FECHA1+4(2) .
year = FECHA1+0(4).

if mon = '01'.       "need to use this 
year = year - 1.     "----> 
mon = '12'.
endif.

concatenate year mon into fecha.
write:/ fecha.

Hi victoria,

1. use this FM

HR_JP_ADD_MONTH_TO_DATE

2. in that give IV_MONTHCOUNT = -1.

regards,

amit m.

[RaymondGiuseppi]

Use CCM_GO_BACK_MONTHS

*" IMPORTING

*" VALUE(CURRDATE) LIKE SY-DATUM

*" VALUE(BACKMONTHS) TYPE NUMC3

*" EXPORTING

*" VALUE(NEWDATE) LIKE SY-DATUM
