How does the "are attachments mandatory for leave applications" advanced option work?

To ensure attachments are attached to a leave application, ensure that the “are attachments mandatory for leave applications” checkbox under advanced options on the applicable leave scheme bucket is enabled.

      Navigate > Configuration > Human Resources > Leave Administration > Leave Scheme Parameters > advanced options

                  

Selecting this checkbox will activate three additional (and optional) fields:

      

      1. “force attachment after the second application with an 8 week cycle”

      2. “do not force attachment after/before public holidays or weekends?” (users will be able to specify whether an attachment should be mandatory or not if the leave was
      taken before or after a public holiday or weekend).

      3. “after how many days” (users can insert a numerical value in the textbox, to specify how many leave days applied for an attachment will become mandatory).
