Customer Program did not calculate Accrual

We have a customer volume program defined with the following rebates:

1. 0 - 500,000 - 0% rebate
2. 500,000 - 1,000,000 - 1% rebate

We created a sales order for $400,000 and invoiced it.

Submitted the following scheduled processes:

1. Load Transactions
2. Create Accruals for Volume Programs
3. Update Customer Accruals Summary

The system did not create any accruals.

My expectation is that the system will calculate a 1% accrual under the assumption that the customer will meet the Tier, and if the customer does not meet the Tier target of $500,000, the system will reverse the accrual.

Please suggest if this is the system's standard behavior of not calculating accruals until the customer's sales reach $500,000
