Deduct sequence means that this will deduct the leave according to the priority that has been set in the system. Whatever leave you have applied, it will deduct based on the fixed settings in the system, i.e. even if you apply sick leave first, it will deduct your annual leave only because of the set preference.

Stores the different types of leave for the deduct sequence. This is the primary key for the DeductSequence table.
Example: Absent / Annual / No Pay etc
