Learn how to update a single order line item and generate a billing document using the Update an order line item operation.

1. Determine the following values for the Update an order line item operation:

   • orderLineItemId: The ID of the order line item to be updated. You can obtain the order line item ID by using the Retrieve an order Order Line Item Details page in the UI.

   • itemState: The state of the order line item. This field must be set to SentToBilling for the billing document to be generated.

   • billTargetDate: The date when the order line item is to be billed. The subsequent bill run will pick up order line items based on this date.

2. Use the Update an order line item operation to update the order line item state and bill target date appropriately. The following API updates the state of an order line item to SentToBilling and sets the Bill Target Date for the order line item to 2021-02-01.

   Request	PUT /v1/order-line-items/{orderLineItemId}
   Request Body	{ "itemState": "SentToBilling", "billTargetDate": "2021-02-01" }

3. Use the CRUD: Create a bill run operation to create an ad hoc bill run.
