Handling date to ADD or Substract fixed # of days using standard function

Question

Hi ,
Using the standard functions in XI, is it possible to add or subtract a fixed number of days from the date i get from the input file.
Like, from file I get the date as 25/06/2009.My output should be 05/07/2009 after adding 10 days .
can some one guide how to handle this.
Thanks,
Ven..

Hi Ven,
Here is a  UDF code,which takes date(format:yyyyMMdd) as input and does addition or subtraction operations based on <field 1> value,return the result date(format:yyyyMMdd) as string value.
public String GenerateDate(String date_input, String field1,Container container){
//Here "date_input" and "field1" are inputs for this UDF
int date = Integer.parseInt(date_input);
Calendar cal;
int day = date % 100;
int month = (date/100) % 100 - 1;
int year = date / 10000;
cal = Calendar.getInstance();
cal.set(year, month, day);
/implement addition or subtraction logic here as your needs/
if (field1 == "A")
cal.add(Calendar.DATE, 10);
else if(field == "B")
cal.add(Calendar.DATE, -5);
day = cal.get(Calendar.DATE);
month = cal.get(Calendar.MONTH)+ 1;
year = cal.get(Calendar.YEAR);
date = year * 10000 + month * 100 + day;
return (""+date);
You can use Standard Funtion DateTrans to convert date from your format to the format used in the UDF and vice versa.
