TRIGGER_BE_RETRO is an optional toggle field. If this toggle is ON, this assignment record may be specifically included in an execution of UBRETRO for retroactive wage benefit changes resulting from wage increases. If this toggle is OFF, the UBRETRO program will not pick up any retro benefits to be processed. A "To Be Audited" pay with starting and ending dates that fall within the effective and expiry dates must also exist for UBRETRO to process.
