You can duplicate an accrual using the three dot menu on either the summary or schedule page.
The three dot menu is located on the right on the summary page:
and on the left for the schedule page:
Clicking this opens an add accrual modal pre-poulated with the same data as the duplicated accrual:
and you can edit any details as required before adding it to the schedule.
This is useful if you have accruals that come up time and again and you'd prefer to not re-enter all of the information each time.
Note: the duplicated accrual is not created until you click Add to schedule.
