Learn how to preview and create delivery adjustments using the API by verifying eligible adjustments, determining necessary variables, and executing the creation of adjustments for specified dates.

1. Verify eligible and ineligible delivery adjustments for the subscription through the Preview an adjustment operation, specifying the start date and end date of the adjustment period as 2023-04-01 and 2023-04-02, respectively, and then decide whether to create new delivery adjustments. If yes, perform the next step.
2. Determine the values of the following variables:

   Variable	Description
   subscriptionNumber	The subscription number for which the delivery adjustments are created. Note: You can also specify the accountNumber field instead of this field. If you specify an account number, the account number must be of the subscription owner.
   chargeNumbers	The charge numbers in the subscription for which the delivery adjustment needs to be created. Note: If you don’t specify a charge number, delivery adjustments are created for all charges in the specified subscription or account.
   startDate	Required. In this example, the start date of the delivery adjustment is 2023-04-01 .
   endDate	Required. In this example, the end date of the delivery adjustment is 2023-04-02 .
   exclusion	In case you don’t want to create delivery adjustments for other rate plan charges in the same subscription or account, you can use this field to exclude these charges from your adjustment. You must specify the charge numbers and the corresponding dates for excluding the charges, using the following nested fields: chargeNumbers : The charge numbers to be excluded from delivery adjustment on the specified delivery date. deliveryDate : The date on which the delivery adjustment has to be excluded, in yyyy-mm-dd format. In this example, the charges you want to exclude from the adjustment may be the charges whose delivery dates are 2023-04-01 and 2023-04-02 .
   type	The value is DeliveryCredit .

3. Use the Create a delivery adjustment operation to create two delivery adjustments for 2023-04-01 and 2023-04-02 for the subscription.
