Change in Default date values

Hi Team,

Hope every one is doing great,My questioon is

I have a Standard Program RMCBMRP2 which is used to fill the MRP Extractor 2LIS_03_S194,Iam executing the Program daily and I get the default dates as From date as sy-datum and To date as 12 days forward ie if todays date is 27th April then the To date will be 9th May,So Now i want the 'To Date' to be 6 months forward ie If todays date is 27th April 2011 then My 'To Date' should be 27th October 2011 and From date should be the same but want to change the To Date only.

Is there any other way other than changing the Standard Program 'RMCBMRP2'.

Please suggest?

Regards,
