Report and Application Approval System

Overview #Personal Development

A general-purpose Approval Workflow Engine that provides unified management of in-company applications from template creation through post-approval auditing. Rather than a single fixed form with an approval button, the focus is on enabling administrators to configure application types, input fields, SLAs, approval routes, and amount conditions, and to operate the entire workflow from definition through application submission, approval, rejection, resubmission, and auditing.

Key Features

• Template Management — Define Dynamic Forms and Conditional Routes for each application type
• 6 Types of Form Fields — Support for Text, Number, Date, Select, Checkbox, and File
• Conditional Branching for Approval Route Determination — Automatically determine approval paths based on numerical conditions such as amounts
• Multi-stage and Parallel Approvals — Support for both serial multi-stage approvals and parallel approvals that wait for all approvers within the same sequence
• Rejection and Resubmission — Rejection with mandatory comments and resubmission with a new version that records changes
• Proxy Approval — Support for proxy approval settings within valid periods
• SLA Management — Deadline approaching and deadline exceeded determination with filtering in Inbox
• Audit Logging — Append-only Audit Trail including SHA-256 chain verification
• Role-Based Access Control — 8 roles: Employee, Manager, Director, Finance, Legal, Executive, Admin, and Auditor
