Creating and Maintaining Nonstandard Semi-Monthly and Monthly Pay and Work Periods
You can create pay or work periods for nonstandard semi-monthly and monthly pay plans using Nonstandard Pay and Work Period Entry (PR21.4). Work and pay periods must be continuous and non-overlapping.
To make corrections to periods that you have already entered, you must delete them and then re-create them with the correct dates.
If you need to change the end date of the first work period or pay period, you must create a new pay plan record with a later effective date on Pay Plan (PR21.1).
