ABAP code for Julian date conversion

_________________________________________

DATA: jdate(7) VALUE '2011348',

gdate TYPE sy-datum,

days TYPE i.

CONCATENATE jdate(4) '0101' INTO gdate.

days = jdate+4(3).

gdate = gdate + days.

Hi,

You can try with standard date function "TransformDate".

In the function set parameters as below

please use format of source date as: yyyyD

and target format as : MM/dd/yyyy

I feel there is no need of an UDF.

DateTrans Standard function will cover this feature. You dont really need to for UDF on this. Provide input what you get and specify output how you want.

Thanks guys.

it worked well with standard function.

also, another UDF for future references on this post,

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, Integer.parseInt(Integer.toString(calendar.get(Calendar.YEAR)).substring(0, 2)+inpdate.substring(0, 2)));
calendar.set(Calendar.DAY_OF_YEAR, Integer.parseInt(inpdate.substring(inpdate.length() - 3, inpdate.length())));
SimpleDateFormat simpDate = new SimpleDateFormat("ddMMyy");
return simpDate.format(calendar.getTime());

Hi. Santosh

Tyr this simple UDF.

            String val = "2011348";
            Date myDate = new SimpleDateFormat("yyyyD").parse(val);            
            SimpleDateFormat sdf= new java.text.SimpleDateFormat("MM/dd/yyyy");
            String fecha = sdf.format(myDate);
            return fecha;

Hi. Try this

Don't forget to add the reference.

import java.util.Date;

import java.text.SimpleDateFormat;

       String fecha ="";
        try {
            String val = "2011348";
            Date myDate = new SimpleDateFormat("yyyyD").parse(val);
            SimpleDateFormat sdf= new java.text.SimpleDateFormat("MM/dd/yyyy");
            fecha = sdf.format(myDate);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return fecha;
