**Flag/Setting Purpose: **Check for duplicate customer order numbers in SOP

- When enabled, the validation process of checking for duplicate **Cust Order #** will include all sales transactions (quotes, orders and invoices) and Customer Orders transaction numbers.
  - For Sales transaction, you will receive the warning message  ⚠ *‘Duplicate order number exists’* an option to **View the Transactions** or **Continue to Save**.
  - For Customer Orders transaction, you will receive the warning message  ⚠ *‘Customer order number already in use for Customer Order: [Customer Order No.]'*.
- When disabled, the validation process will NOT look up Customer Orders transaction numbers when the Customer Maintenance flag **Order Number Unique **has been enabled.

> ⚠️ **NOTE**: If the **Customer Maintenance** flag **Order Number Unique **has been enabled, you will receive an error and you will need to enter a unique customer order number to save the order.
