Server scripts — Sales Invoice & payroll

Purpose

Map scripts/ entry points to hooks so engineers know where submit-time and payroll logic lives.

Scope in codebase

• leekimerp/leekimerp/scripts/sales_invoice.py
• leekimerp/leekimerp/scripts/salary_slip.py, payroll_entry.py, salary_component.py, employee.py (see Payroll & HR and Doc events)

Sales Invoice (scripts/sales_invoice.py)

Symbol	Trigger	Role
before_submit_sales_invoice	doc_events Sales Invoice on_update in hooks.py	Expands [Year], [Invoice No], [Customer], [Item Code] in item description lines via _render_template

Flow: On update, each item description is scanned; known bracket tokens are replaced from the invoice and row context.

Maintenance

The handler contains a debug print("asdasd") — remove or replace with structured logging before production hardening.
