EFFECTIVE_DATE_CORRECTION is a toggle which signifies if the PA is dedicated to a date effective correction and ONLY that. No other data changes are permitted in an effective date change personnel action. The ONLY column that will be affected is the effective date column.
If left unchecked the 'Initiate PA' dialog works by creating a PA used to maintain records as of the Takes Effect date field.
If the 'Is Date Correction' toggle is checked the PA effective date field will now display as Old Effective, the update future records and cascade change reason fields will be hidden, and a new effective date field will be displayed. This is to be filled out with the “Old Effecitve” date matching 1 of the original effective dates and the “New Effective” entered to be the new effective date applied during processing of the Personnel Action. When the PA is created the top portion for the PXXX screen will display showing the new and old effective dates.
