How to changes sales order sequence number in ODOO

To change the sequence number format for sales orders in Odoo, follow these steps:

---

1. Navigate to the Sequence Settings:

1. Go to the Settings module in Odoo.
2. Under the “Technical” section, select Sequences & Identifiers > Sequences.
   (Note: If the “Technical” menu is not visible, ensure the “Developer Mode” is enabled. You can enable it from the “About Odoo” section in Settings.)

2. Locate the Sales Order Sequence:

1. Search for the sequence named Sales Order (or SO depending on your Odoo localization).
2. Click on the sequence to open its settings.

3. Edit the Sequence Format:

• The sequence format is defined in the “Prefix” and “Sequence Number” fields.
  Examples:
  • SO/{year}/{month}/ will generate sales orders like SO/2024/12/001.
  • SO- will generate sales orders like SO-00001.

Adjust Key Fields:

• Prefix: Defines the prefix for the sequence. You can include placeholders like:
  • {year}: Current year.
  • {month}: Current month.
  • {day}: Current day.
• Padding: Defines the number of digits in the sequence number (e.g., 5 means 00001).
• Next Number: Defines the next number that will be generated.

---

4. Save the Changes:

• Once you modify the sequence settings, save your changes.
• Future sales orders will use the updated sequence format.

Optional: Apply the New Sequence to Existing Orders

If you want to update existing sales orders with the new sequence format, it will require a database update through an Odoo script or manual edits via the backend. Let me know if you need help with this!
