AL No. Series Update for Business Central

Overview

AL No. Series Update provides a controlled mechanism to update number series in Business Central based on the current year. The app applies per-numerator logic and updates only those numerators that meet defined rules, ensuring safe and accurate year-based numbering.

Key Features

• Updates individual numerators via a manual report
• Automatically calculates the reference year based on execution date
• Checks that the numerator prefix contains the two-digit year
• Verifies the last number assigned against the calculated reference year
• Updates only compliant numerators, skipping others
• Deterministic and repeatable operation

Reference Year Logic

• Execution between January and June: reference year = current calendar year
• Execution between July and December: reference year = next calendar year

Update Rules

For each numerator in the number series, the following checks are applied:

1. Year in Prefix
   The numerator prefix must include the two-digit year. If not present, the numerator is skipped.

2. Last Number Year Check
   The year of the last assigned number is compared with the calculated reference year. If it does not match, the numerator is skipped.

Only numerators passing both checks are updated. All others remain unchanged.

Usage

• Exposes a manually executable report
• No additional configuration required
• Updates only eligible numerators in the series
• Idempotent and safe for repeated execution

Scope

• Standard Business Central tables related to number series
• No third-party dependencies
• No modifications outside the relevant numerators

Security and System Impact

• No automated background execution
• No external integration or data transmission
• Changes limited strictly to numerators compliant with the rules

Purpose

The app provides a precise, selective, and safe tool for annual number series updates. It ensures that only numerators conforming to formatting and year consistency rules are updated, minimizing the risk of incorrect modifications.
