Calendar working days and holidays for Oracle EBS R12 Absence management

1. 1. Build 2 functions inside your package
FUNCTION calculate_working_days (p_sd DATE, p_ed DATE)
RETURN NUMBER
IS
v_days_between NUMBER;
v_count NUMBER;
v_count_off_days NUMBER := 0;
l_grade_cat VARCHAR2 (1000);
l_territory VARCHAR2 (1000);
v_working_days NUMBER := 0;
CURSOR crs_off (p_column_name VARCHAR2, p_territory_name VARCHAR2)
IS
SELECT DECODE (p_territory_name,
'AMERICA', DECODE (c.row_low_range_or_name,
'Saturday', '7',
'Sunday', '1',
'Monday', '2',
'Tuesday', '3',
'Wednesday', '4',
'Thursday', '5',
'Friday', '6',
c.row_low_range_or_name
),
DECODE (c.row_low_range_or_name,
'Saturday', '1',
'Sunday', '2',
'Monday', '3',
'Tuesday', '4',
'Wednesday', '5',
'Thursday', '6',
'Friday', '7',
c.row_low_range_or_name
)
) weekday_name
FROM pay_user_tables a,
pay_user_columns b,
pay_user_rows_f c,
pay_user_column_instances_f d
WHERE a.user_table_name = 'ZZZ_WEEKDAYS'
AND b.user_column_name = 'WORKDAYS'
AND a.user_table_id = b.user_table_id
AND a.user_table_id = c.user_table_id
AND d.user_column_id = b.user_column_id
AND d.user_row_id = c.user_row_id
AND d.VALUE = '0';
BEGIN
SELECT VALUE
INTO l_territory
FROM nls_session_parameters
WHERE parameter = 'NLS_TERRITORY';

2. v_days_between := fffunc.days_between (TRUNC (p_ed), TRUNC (p_sd)) + 1;
FOR i IN 1 .. v_days_between
LOOP
FOR rcrd_off IN crs_off (l_grade_cat, l_territory)
LOOP
BEGIN
IF TO_NUMBER
(LOWER (TRIM (BOTH ' ' FROM TO_CHAR ( TRUNC (p_sd)
+ (i - 1),
'D'
)
)
)
) = TO_NUMBER (LOWER (rcrd_off.weekday_name))
THEN
v_count_off_days := v_count_off_days + 1;
END IF;
END;
END LOOP;
END LOOP;
v_working_days := v_days_between - v_count_off_days;
RETURN NVL (v_working_days, 0);
END calculate_working_days;
FUNCTION CALCULATE_CALENDAR_DAYS(p_sd DATE, p_ed DATE) RETURN NUMBER AS
V_CALENDAR NUMBER := 0;
BEGIN
select max(a) INTO V_CALENDAR FROM (SELECT NVL(cal.end_date -
cal.START_DATE +1,0) A
from per_calendar_entries_V cal
where TRUNC(cal.START_DATE) between TRUNC(p_sd) and (p_ed)
UNION ALL SELECT 0 FROM DUAL) ;
RETURN V_CALENDAR;
EXCEPTION
WHEN OTHERS
THEN
V_CALENDAR := 0;
RETURN V_CALENDAR;
END CALCULATE_CALENDAR_DAYS;
2. go to (Define function) and Define those functions inside application

3. 3. define table, columns and row data

4. Now we can use the function calculate_working_days inside ur
bg_absence_formula
4. go to enter and maintain events (work structer-> calendar events-> )
5. define calendar events like (Eid al feter)
6. now you can use the function CALCULATE_CALENDAR_DAYS inside
bg_absence_formula
good luck …
