Hi Dude,

Use this Function Module(RKE_CONVERT_DATE_TO_PERIOD) to get the previous 3rd month date.

Pass the parametrs as

Import parameters Value

DATE 22.08.2008 "sy-datum

PERFLAG 1

PERIV V3

Then U will Get the Outputput as

PERIO 005.2008

U will get the Month and the year, Now u Use

sy-datum+0(2) u will get the date i.e 22.

PERIO+1(7) u will get 05.2008

now concatenate 22 and 05.2008 separated by '.'.

Hope this helps u.

Thanks RAM,

But i have used fm to calculate the Date my main Problem is i am Unable to pass that Value to the Import parameter:

That is from se37 if we execute the FM u will get the Import Parameters at that time this date also should come, But it's not comming .

Thanks in advance.

Hi Dude,

Click on the Source Code Tab

and Write the Code.

This code should contain i_param = v_Date.

where i_param is Ur import parameter name.

v_Date is Ur calculated Date.

Keep break-point and execute.

Hi Nagaraju,

If this is the case i can suggest you a way to do this....

Make the import parameters(TO and From Dates) as optional..

And Inside the function module check if the import parameters are initial, if the values are not supplied, generate it yourself using the code i gave above....

If u want to supply value from a program, use the above code in the program and supply the To and From date in the function call.

So now if u go to SE37 and execute it without supplying values, it will get calculated inside the Function Module itself, in case u supply it will take it for calculation.

Hope this will work well for your requirement.

Hi,

Use the Following FM....

MONTH_PLUS_DETERMINE Add or subtract months from a date. To subtract a month, enter a negative value for the 'months' parameter.

Example:

data: new_date type d.

CALL FUNCTION 'MONTH_PLUS_DETERMINE'
  EXPORTING
    months        = -5       " Negative to subtract from old date, positive to add
    olddate       = sy-datum
 IMPORTING
   NEWDATE       = new_date.
