Check the next number#

Choose the document type whose next number you want to change. Finance should approve the sequence first.

Set the numbering rule#

  1. 1
    Open Numbering and select the document type.
  2. 2
    Enter Prefix and Suffix if needed, set Zero-Padding Digits, and choose the Reset Period and Timezone.
  3. 3
    Set the Next Sequence Number, review Live Preview, then save.
  4. 4
    Read Live Preview and compare it with the next number your team expects.
  5. 5
    Create a draft document and confirm the sequence displays as configured.

A number already issued belongs to its original document; change future numbering carefully.

Confirm the sequence#

Reopen the rule and check its preview. Previously issued document numbers do not change.

WARNING: Changing the Next Sequence Number, Prefix, or Reset Period can create gaps or collisions in external records. Finance should approve the numbering policy before the change.
