Create Schedule Function 

1. Click in the upper-right corner.
   
2. Navigate to Developer Space > Schedule Functions.
   
3. Click Create Schedule Function.
   
4. Enter a Function Name, and Description, and set the Arguments.
   
5. Set the Scheduled Date and Time for the first execution.
   
6. Choose Repeat Types based on your preference.
   
1. Once: The Schedule Function will only run once at the specified date and time. No further executions will occur.
   
2. Hourly: Choose this if you want your function to run repeatedly at hourly intervals. Specify the desired interval in hours in the Repeat Every field, and the function will execute every 'A' hour (e.g. every 2 hours or every 4 hours).
   
3. Daily: Select the number of days between each execution. Choose 1 for daily execution, 2 for every other day, and so on from the Repeat Every field.
   
4. Weekly: Define every 'A' week in the Repeat Every field. Select the desired days ('Monday', 'Tuesday', etc.) from the Repeat On field, and the function will run only on those days every 'A' week.
   
5. Monthly: Choose every 'A' month from the Repeat Every field. Choose specific dates of the month (e.g., 1st, 15th, etc.) by selecting A specific day from Repeat On field. You can also select to execute the function on the last day of the month, or on the Nth day (e.g., second Friday, third Thursday, last Friday) from Repeat On field.
7. Specify End Conditions to determine when the Schedule Function will end.
1. Never: The function will continue to run indefinitely until manually stopped.
   
2. On: Specify a specific date (e.g., 12-03-2024) as the final execution date. The function will conclude at the end of the day of the given specific date.
   
3. After: Enter the desired number of times the function should run before it stops.
8. Control how your function behaves on Holidays.
   
1. Execute Schedule: The function will run even on holidays.
   
2. Skip Schedule: This skips the Schedule Function if a holiday is encountered, and the next cycle begins according to your specified Repeat Types. 
   
3. Execute on Previous Working Day: The function will shift its execution to the previous working day.
   
4. Execute on Next Working Day: The function will shift its execution to the next working day.
   
9. Scroll down and type in your code in the Deluge script editor or drag and drop the parameters available in the left panel of the editor and customize them.
   
10. Click Schedule to save and schedule, or click Execute to run the function right away.

1. The Schedule Function will be skipped (similar to the Skip Schedule option) if the previous working day has already passed the scheduled time. 

1. The schedule automatically stops upon encountering 10 consecutive holidays or weekends when the holiday behavior is set to Skip Schedule, Execute on Previous Working Day, or Execute on Next Working Day.
