i have done the settings that you mentioned.  but it merged all the sales lines in one purchase order.

my query is if my product is same and vendors are different then what will i do.

eg.

my sales order lines are 

product    qty   rate  amount

gulab        10     100   1000
gulab        10     100   1000
gulab        10     100   1000

here vendors for all the 3 sales lines are different.

so my requirement is for same product i want to create 3 different purchase orders. 

how can i achieve this.

​In Odoo, when managing sales orders that require procurement from multiple vendors, it's essential to configure products and procurement routes appropriately to ensure that each sales order line generates a separate purchase order corresponding to its designated vendor. Here's how you can achieve this:​

1. Configure Each Product with Its Respective Vendor:

• Access Product Information:
  • Navigate to the Sales or Purchase module.​
  • Select Products and choose the product you wish to configure.​
• Assign Vendor to Product:
  • Go to the Purchase tab within the product form.​Odoo+2Odoo+2Odoo+2
  • In the Vendors section, add the specific vendor associated with this product.​
  • Repeat this process for each product, ensuring that each one is linked to its respective vendor.​

2. Enable and Configure Procurement Routes:

• Activate Multi-Step Routes:
  • Navigate to Inventory > Configuration > Settings.
  • Under the Warehouse section, enable Multi-Step Routes and save the changes.​
• Configure Routes for Each Product:
  • In the product form, under the Inventory tab, select the appropriate routes:​
    • Buy: Indicates that the product is purchased from a vendor.
    • Replenish on Order (MTO): Ensures that a purchase order is created for each sales order line.
  • Ensure that both routes are selected for each product.​

3. Adjust Procurement Group Propagation Settings:

• Modify Route Rules:
  • Go to Inventory > Configuration > Routes.​
  • Locate and edit the Buy and Replenish on Order (MTO) routes.
  • For each route, adjust the Propagation of Procurement Group setting to Propagate. This configuration ensures that each sales order line maintains its procurement group, leading to the creation of separate purchase orders.​

4. Create and Confirm Sales Orders:

• Generate Sales Order:
  • Navigate to the Sales module and create a new sales order.​
  • Add multiple products, each associated with different vendors, as separate sales order lines.​
• Confirm the Sales Order:
  • Upon confirmation, Odoo will automatically generate individual purchase orders for each sales order line, directed to the respective vendors.​

By meticulously configuring each product with its specific vendor and appropriately setting up procurement routes and rules, Odoo will facilitate the automatic creation of separate purchase orders for each sales order line, aligning with your procurement requirements.​
