To change the FTE Hours on a post:
Go to Admin Menu and select Post Setup.
Search for the post and click on it.
Scroll down to Pay Details and click Edit.
Amend the FTE Hours field and click Save.
You may not be able to edit the FTE hours on the post if the negotiating body linked to it already has an FTE hours value added. In this case you will need to review the value added on the negotiating body and amend it if needed:
Go to Setup and click Settings.
Select Module Settings and the Payroll Settings.
Click Pay Grade and Payscale.
Click on the name of the negotiating body.
Amend the value in the FTE Hours field and save.
