Credit Check Funtionality

Dear Experts,

I'm trying credit check functionality for the first time and found it's not working as expected after completing the basic setups (Doc ID 444837.1).

Please advise whether any necessary setup is missing.

1. Assigned existing credit check rule to order type (ordering & Shipping)

2. Checked credit check box at customer & site profiles including currency, credit limit and order limit

3. Checked credit check box at Payment Term defined in the customer

4. Report 'Initialize Credit Summaries Table' completed normal

5. Report 'Credit Exposure Report' completed normal

6. Created a sales order for a customer with credt limit as 500 USD which got an outstanding Invoice# 10310537 for amount 2,432.97 USD.
