# Walkthrough - Overtime Delegation API Implementation

I have implemented the backend API for Overtime Delegation as requested. This API allows superiors to delegate overtime tasks to multiple subordinates across a range of dates.

## Changes Made

### 1. Delegation Service
- **File**: [delegation-overtime-services.js](file:///home/itc43/Documents/HOKBEN_PROJECT/ESS%20PROJECT/ess_api/ess_api/app/services/delegation-overtime-services.js)
- **Method**: `insertOvertimeDelegation`
- **Logic**: 
    - Accepts a payload with employees, date range, and times.
    - Generates a unique `idplanning` for tracking the batch.
    - Calculates the duration for the overtime.
    - Performs a batch `INSERT` into the `trx_multi_ovt` table.
    - Includes tracking fields: `nik_delegator`, `time_stamp_delegator`, `nik_delegate`, `name_delegate`, and `time_stamp_delegate`.

### 2. Delegation Routes
- **File**: [delegation-routes.js](file:///home/itc43/Documents/HOKBEN_PROJECT/ESS%20PROJECT/ess_api/ess_api/app/routes/delegation-routes.js)
- **Endpoint**: `POST /api/delegations/overtime/insert`
- **Middleware**: Secured with `jwtAuth.verifyToken`.

### 3. Server Integration
- **File**: [server.js](file:///home/itc43/Documents/HOKBEN_PROJECT/ESS%20PROJECT/ess_api/ess_api/server.js)
- **Action**: Registered the new delegation routes.

## Verification
- The API is now ready to be consumed by the UI.
- The batch insertion logic ensures that multiple records are created efficiently.
- Tracking fields are populated to allow auditing of who delegated to whom.

## Next Steps
- Update the Flutter UI (`OvertimeDelegationPage`) to call this new API endpoint when the "Submit Delegasi" button is pressed.
