Can Contract and Service Billing 9.1 check Customer Credit Limit?

I cannot find where Contract and Service Billing 9.1 has a mechanism to check the Customer Credit Limit when the original Contract and original Budget are entered.  We have cases where we use Standard Sales Orders for a Customer (product sales), and we bill the same Customer via Contract Billing for a specific project (products and services).  Is there a way to configure the original contact/budget such that JDE will include the Original Budgeted Billing amount in the Credit Limit calculation, and return a Credit Hold code?  Thanks.
