Estimation Based Usage Subscription

Summary:

Creating subscription with estimation amount/quantity and minimum quantity/amount through sales order.

Content (please ensure you mask any confidential information):

We are creating a subscription with estimated and actual based usage. When the subscription is in draft status, estimated quantity/amount and minimum quantity/amount can be manually entered to generate estimated and actual billing lines.

But while creating the sales order, I dont see any field to enter the estimated quantity/amount and minimum quantity/amount to be interfaced into subscription.

Is there any field in sales order to enter the estimated quantity/amount and minimum quantity/amount? Subscription interfaced from sales order is in active status, hence I cant entered estimated quantity/amount and minimum quantity/amount
