Customers can go on credit hold in one of two ways: 1) They can be manually placed on hold or 2) they can go on credit hold because their accounts receivable (A/R) balance has exceeded their pre-defined credit limit. A customer's credit limit is set on the customer master. When customers are on credit hold, certain activities—such as shipping sales orders—will be prevented. Customers come off credit hold when their A/R balance falls below their credit limit. You also can take a customer off credit hold manually.
