DaysBack and InvalidateRoster fields control how far back shift updates are processed and whether affected rosters are invalidated after the update of real employee states.

Update only current day shifts

{
"DaysBack": 0
}

Reprocess shifts from previous days

"DaysBack": 10
}

Invalidate roster after real attendance updates

{
"InvalidateRoster": true
}

Update shifts without roster invalidation

Useful when shift updates should not trigger additional roster recalculations for performance or operational reasons.

{
"InvalidateRoster": false
}
