Tell about the entire data and product flow — how the supply to the warehouse occurs, how data passes through systems?

The data and goods flow during warehouse delivery usually includes several key stages:

1. Receiving goods from the supplier:

   • The supplier sends the goods with accompanying documentation (invoices, specifications).
   • The goods are received at the warehouse, checked for compliance in quantity and quality.

2. Registering goods in the system:

   • Data about the goods (article number, quantity, characteristics) are entered into the warehouse management system (WMS).
   • A record of the batch of goods is created with a unique identifier.

3. Placement in the warehouse:

   • The goods are placed in designated storage locations.
   • Information about the location is updated in the system.

4. Data processing:

   • Integration with the ERP system for inventory and financial accounting.
   • Automatic updating of stock levels and product availability for sales.

5. Shipping and further operations:

   • When an order is placed, the goods are reserved and prepared for shipment.
   • Data on the movement of goods is updated in real-time.

Technically, the data passes through several systems:

• Receiving system: scanning and data entry.
• WMS: warehouse management, accounting, and logistics.
• ERP: financial and managerial accounting.
• Integration buses or APIs: for data synchronization between systems.

An example of a simplified flow in Go (pseudocode):

func ReceiveShipment(shipment Shipment) error {
    err := ValidateShipment(shipment)
    if err != nil {
        return err
    }
    err = RegisterInWMS(shipment)
    if err != nil {
        return err
    }
    err = UpdateERP(shipment)
    return err
}

Thus, the process of delivery and data processing is a chain of interconnected operations with quality control and synchronization between systems.
