Makeup in Zdoo means that you have asked for a leave and you want to make up for it by working for the hours that you have asked for the leave.
Zdoo 4.2+ has this Makeup feature added, so it is more convenient for companies to manage leaves.
Firstly, go to OA->Settings to turn on the Makeup feature.
Then, go to OA->Makeup. Click Apply to create a makeup. The premise of applying a makeup is that you have asked for leaves, so you will be able to choose from the Leave drop-down on the application form.
The application will be displayed in the list and wait for the manager to review it. The applicant can edit, delete or cancel the application.
For reviewers, go to My Review to Pass or Reject the application.
