Feature Request: Auto Submission of Orders from EPOS Manager to Suppliers

Description:
We need the EPOS Manager system to automatically submit purchase orders to our suppliers based on predefined schedules. Our internal system will generate and submit the purchase orders or templates to EPOS Manager. EPOS Manager will then need to automatically forward these orders to the respective suppliers at set times during the day. Each supplier may have different submission times, and these times may vary depending on the day of the week (weekdays vs. weekends).

Acceptance Criteria:

1. Order Submission Timing:

   • EPOS Manager must be capable of handling different submission times for each supplier.

   • Supplier submission times should be configurable by day of the week (weekdays vs. weekends).

     • Example: Supplier A may require orders to be submitted at 10:00 AM on weekdays and 12:00 PM on weekends.

     • Example: Supplier B may require orders to be submitted at 2:00 PM on weekdays and 3:00 PM on weekends.

2. Integration with Internal System:

   • The internal system will send the purchase order or template to EPOS Manager. The system must:

     • Accept orders in a predefined format (e.g., JSON, XML).

     • Log or acknowledge receipt of the order with a timestamp.

3. Automatic Order Submission:

   • Once the internal system sends the order to EPOS Manager, the system will automatically forward the order to the correct supplier at the scheduled time.

   • Orders should be submitted to the supplier without any manual intervention from staff.

   • The submission should occur consistently at the designated time without delays or failures.

4. Error Handling and Notifications:

   • If an order submission fails (e.g., due to network issues, supplier downtime), EPOS Manager should:

     • Retry submission at a set interval (e.g., after 5 minutes).

     • If retrying fails, the system should log an error and notify the relevant stakeholders (e.g., via email or dashboard alert).

5. Logging and Auditing:

   • All order submissions should be logged with the following details:

     • Order ID

     • Supplier Name

     • Submission Timestamp

     • Success/Failure Status

   • This log should be accessible for troubleshooting and auditing purposes.

6. Supplier-Specific Configuration:

   • The system must allow different configurations for each supplier, such as:

     • Custom submission times per supplier (both weekdays and weekends).

     • Ability to temporarily disable order submissions to a supplier if necessary.

7. Performance and Reliability:

   • The system must handle simultaneous order submissions to multiple suppliers without impacting performance.

   • The system should be resilient to network disruptions and ensure that all orders are eventually processed.

8. Testing:

   • Ensure that the system is tested with different supplier configurations (e.g., varying submission times, network delays) to verify reliability.

   • Test the error handling flow (e.g., retries, alerts).
