If you leave the field blank when creating new pallets, and you set up a number sequence for the pallet identification (ID), the pallet will be given an ID automatically when the record is saved.

If the length of the field set up for the number sequence is exactly 17 and permits only numbers, Microsoft Dynamics AX assumes that you are using pallet ID's according to the SSCC-18 standard. Therefore, it will automatically calculate and attach a check number as character number 18.
