# BC Friday Tips #59 Allocation Account Design

[Read the post](https://thatnavguy.com/blog/2025/bc-friday-tips-59-allocation-account-design/) · That NAV Guy (Teddy Herryanto, MVP) · 2025-12-05 · 94 words · tier community · reviewed (checked by Opus)

> Allocation Accounts automate the distribution of revenue or cost amounts through journals and documents. The feature is implemented via Codeunit 2677, which subscribes to an event before posting batch runs, intercepts journal lines, rewrites them, and posts the updated lines.

## Key points

- Allocation Accounts distribute revenue or cost amounts automatically across journals and documents
- The AL implementation lives in Codeunit 2677 'Gen. Journal Alloc. Acc. Mgt.'
- The codeunit subscribes to an event that fires before Gen. Jnl.-Post Batch runs
- Journal lines are intercepted, rewritten, and then posted
- Understanding this pattern helps with debugging and implementing similar functionality

## Quotes

- "Allocation Account automates how revenue or cost amounts are distributed through journals and documents" (Explains the core purpose of the feature for automating distribution workflows)
- "It intercepts the journal lines, rewrites them, and then posts the updated lines." (Shows the technical mechanism used to implement allocation without changing the posting framework)

## AL objects mentioned

- [codeunit 2677 "Gen. Journal Alloc. Acc. Mgt."](../../objects/codeunit/2677.md)
- [codeunit 13 "Gen. Jnl.-Post Batch"](../../objects/codeunit/13.md)

## Context

- Features: Allocation Accounts, journal distribution, revenue allocation, cost allocation, event-based processing
