Restrict Users from Creating a Stand Alone Sales Order using SuiteFlow

To Restrict Users from Creating a Stand Alone Sales Order using SuiteFlow

We can restrict users from creating directly from Transactions> Sales> Enter Sales Order if user follows the estimate to order process.

The unique identifier for Orders created from estimate and created directly was Created From. Users just need to use it as a condition.

However, this field is not available when Orders is not created from any estimate.

Below would be the settings of the Workflow that would restrict the order creation directly :
