Learn how to generate Charge Segment records for Inflight Quotes by enabling specific settings and executing code snippets in Zuora in Multi Subscription Quoting.

1. Open the Developer Console and select File > New > Apex Class.

   Alternatively, go to Setup and create a new Apex class.

2. Name the class PreviewMSQBatchable.

   If you use a different name, ensure to update the class name in the code snippet provided in this article.

3. Paste the code snippet provided in this article into the new class and click Save.
4. In the Developer Console, click Debug > Execute Anonymous Window and paste the following three lines.

   These lines are also included in the commented section at the top of the larger code snippet.

   List<String> parentQuoteIds = new List<String>{'001xx000003DGAXAA4', '001xx000003DGAXAA5', '001xx000003DGAXAA6'}; BatchPreviewMSQ batchJob = new BatchPreviewMSQ(parentQuoteIds); Database.executeBatch(batchJob, 1); // Must process 1 quote per batch

5. Enter the Parent Quote IDs you want to trigger into the SOQL query string.
6. Ensure the quotes you include in the query string have the zqu__MSQ_AsyncRequestStatus__c field is empty.
7. Execute the code in the Debug > Execute Anonymous Window.

   Code snippet

   /**
    * Batch class to process multiple MSQ previews
    * To execute, paste the following three lines into Anonymous window:
    * 
    * List<String> parentQuoteIds = new List<String>{'001xx000003DGAXAA4', '001xx000003DGAXAA5', '001xx000003DGAXAA6'};
    * BatchPreviewMSQ batchJob = new BatchPreviewMSQ(parentQuoteIds);
    * Database.executeBatch(batchJob, 1); // Must process 1 quote per batch
