scmc.InvoicingTaxCalculationBatch

global with sharing class InvoicingTaxCalculationBatch implements Database.Batchable<sObject>, Database.AllowsCallouts, Database.Stateful

Enables you to calculate tax using Avalara for multiple invoices in a batch job.
You can provide a list of IDs representing the invoices that you want to calculate tax for. Once tax is calculated, you will receive an email with the number of successfully processed invoices and the number of errors. The errors are also stored in your org as error log records (SCMC__Error_Log__c).

Note:

The tax calculation using Avalara AvaTax must be enabled in your org before you can use this service. For more information, see the Order and Inventory Management Help.
Due to a limitation, set the maximum batch size to 1 for optimal efficiency.

This class implements the Salesforce Database.Batchable class. This enables you to:

Use the Database.executeBatch method to run the batch job.
Use the System.scheduleBatch method to schedule the batch job to run once at a future time.

For more information about using batch Apex, see the Salesforce developer documentation.
