Have you noticed that your Production Adjustments/Write Offs are showing dates outside of the selected date range in your Performance Board - Adjustments/Write Offs source details?

This happens when your Production Settings are set to Procedure Date. This means that any Adjustment / Write Off that occurs for a procedure during the selected time frame will show up in the source details. To view these settings follow the steps below:
Go to your Settings by hovering over your initials in the bottom left hand corner
Access the General Settings
Click into Production Settings

Example:
A filling is performed on 5/12.
With the Procedure Date setting selected, if an Adjustment were made on the ledger on 7/2, the adjustment would show up on the source details list of May adjustments because this was made to a procedure performed in the time frame selected.
