Number Sequences

The Number sequences configuration page is a core architectural component of the ERP system. It dictates the automated generation of unique, consecutive, and strictly formatted identifiers for every transactional record and master data entity across all modules (e.g., generating CUST-000001 for a new Customer or INV-2026-00045 for a Sales Invoice).

Establishing a robust number sequence strategy ensures a rigid audit trail, prevents document duplication, and aligns system records with your physical filing nomenclature.

Accessing Number Sequences​

Navigate to Organization administration > Number sequences.

The primary view presents a comprehensive grid of all configured sequences within your legal entity. The grid details the sequence Name, its underlying Format mask, the numeric boundaries (Smallest and Largest), the Next Value to be issued, and its current operational Status.

Creating a New Number Sequence​

Click the + New button on the action toolbar to define a new sequence.

Basic Information​

This section establishes the foundational identity and behavior of the sequence.

  • Name: A descriptive identifier for the sequence (e.g., Customer, GL-Journal, Free-Text-Invoice).
  • Format: The alphanumeric mask that dictates how the identifier is constructed.
    • Use the hash symbol (#) to denote the auto-incrementing numeric segment.
    • Examples:
      • CUST-###### will generate CUST-000001, CUST-000002.
      • INV-(####) will generate INV-(0001).
  • Current value: Indicates the last number that was successfully generated and committed. For a brand new sequence, this typically defaults to 0.
  • Next value: Indicates the numeric value that will be issued upon the next request. This typically defaults to 1 for a new sequence.
Alphanumeric Masks

The alphanumeric prefix and suffix in your format mask are entirely static. Only the segment composed of # characters will increment. Ensure you allocate enough # characters to accommodate your long-term transactional volume to avoid exhausting the sequence (e.g., ###### allows for 999,999 unique records).

Number Sequence Details and References​

When inspecting an existing number sequence (by clicking on a record in the grid), the interface reveals two additional critical sections beyond the Basic Information.

References​

The References grid is read-only and displays exactly where this specific number sequence is currently bound within the ERP's module parameters.

  • Module: The overarching business domain (e.g., Accounts receivable, General ledger).
  • Data Type: The specific entity or transaction type consuming the sequence (e.g., Customers, General journal transfer).
Sequence Binding

You cannot delete or heavily modify the format of a number sequence if it is actively bound to a parameter reference. The sequence is locked to preserve referential integrity across the bounded module.

Audit Information​

This section provides an immutable system log detailing when the sequence was instantiated and subsequently modified, complete with the user identifiers (Created by, Modified by) and timestamps, satisfying strict IT audit requirements.
