Validate duration of Edit Entries lines

Summary

How to validate duration of the entry lines when adding an absence request with 'Edit Entries' (Advanced Entry)

Content

Hi,

Our client has three requirements:

• Absence types should count in hours (elapsed work schedule, combined with timecards and TOIL in hours, only works well with other absence types in hours)
• The 'Edit Entries' functionality should be available when adding or modifying an absence request  (ease of use for users: less separate absence requests).
• Users should only request absences in increments of half a day. Because of differences in working schedules, the amount of hours that constitutes half a day differs.
