how to set the current date field to previous Sunday in peoplesoft

Question

I'm new to Peoplesoft and just trying to set the current date field to previous Sunday and for that I have used the 'weekday' function but this is returning an integer value. How can I convert the returned integer value to the date? Can anyone help me out with this issue? Thanks in advance.

Answer 1

i assume you know how many days before was last sunday, in that case you can use this function

AddToDate(date, num_years, num_months, num_days)

it will return a date

example

AddToDate(Date(),0,0,-3), assuming sunday was 3 days before today

Answer 2

Assuming that you want the last sunday, so for example today is 30/06/2015 then the previous sunday is 28/06/2015.

to do that you can use

Local date &dt = %Date;

Local number &num = Weekday(&dt);
WinMessage(Date(&dt - (&num - 1)), 0);

Weekday function returns number value from 1 (sunday) to 7 (saturday). So if you know the today's date (%date) then get the weekday from it.

If you want to get another date other than current date then use DateValue(date_str) where date_srt is the string value of the date you want.

another way of doing this is

SQLExec(select To_date(:1,'DD/MM/YYYY') - (To_Char(To_date(:1,'DD/MM/YYYY'), 'D') -1) from dual, &dtValue, &dtSunday);

substitute &dtValue to the date you want

Answer 3

Here is the code:

%Date is used to retrieve SYSDATE. I have added a few comments to validate the result.

/* Code Begins Here */

Local date &dtSunday;

Local integer &i;

MessageBox(0, "", 0, 0, "SYSDATE - " | %Date);

MessageBox(0, "", 0, 0, "Previous Sunday - 28-June-2015");

&i = Weekday(%Date);

&dtSunday = AddToDate(%Date, 0, 0, - (&i - 1));

MessageBox(0, "", 0, 0, "Computed Sunday - " | &dtSunday);

/* Code Ends Here */

Here is the result:

SYSDATE - 2015-07-02 (0,0)

Previous Sunday - 28-June-2015 (0,0)

Computed Sunday - 2015-06-28 (0,0)
