Custom Numbering Callback Class
You can stamp custom number on the invoices by adding a callback class for Invoice Numbering.
To add the custom class
- Go to Setup > App Setup > Develop > Apex Classes.
- Click New.
- Enter the sample callback class code.
-
Click Save.
Note: This is just a sample callback class. You may change the code per your requirements.Warning: In order to implement the interface, prefix it with Apttus_Billing.CustomClass.<Interface Name>
/** * Apttus Billing * DefaultCustomNumberingCallback * * @2011-2016 Apttus Inc. All rights reserved. */ public with sharing class DefaultCustomNumberingCallback implements CustomClass.IFacilitateCustomTransactionNumbers { /** * Evaluate the "object type" of the specified numbering configuration settings and determine * if the settings are valid for your custom implementation. For example, the default Apttus * implementation of this interface for the "Invoice" object type expects that only "field 1" has * been checked. This is critical because the user interface for the custom number entries * uses the numbering configuration setting object to determine which fields to force the * user to enter. Any field unchecked will be hidden from the user. * * @param customNumberingConfigSetting The custom number configuration setting to evaluate. * * @return true if the "custom numbering configuration settings" is valid for its underlying "object type", * otherwise return false. */ public boolean isValidConfiguration(CustomNumberingConfigurationSetting__c numberingConfigSettings) { if (numberingConfigSettings.ObjectType__c.equals(CustomClass.CUSTOM_NUMBERING_OBJECT_TYPE_INVOICE)) { if (true == numberingConfigSettings.FieldOneEnabled__c && false == numberingConfigSettings.FieldtwoEnabled__c && false == numberingConfigSettings.FieldThreeEnabled__c && false == numberingConfigSettings.FieldFourEnabled__c && false == numberingConfigSettings.FieldFiveEnabled__c) { return true; } } return false; } /** * Build the list of "lookup key" field lists for the each of the * specified Invoices. * * @param invoices The list of Invoices to evaluate and to find the * corresponding list of lookup key field lists for. * @param customNumberingConfigSetting The custom number configuration * setting for Invoices. * * @return the list of lists. Each element of the returned list must * contain the "lookup key" field list for the corresponding Invoice. * The number of lists returned must match the number of Invoices passed in * and the ith list must correspond to the ith Invoice. For example, if * 2 Invoices are passed in, then 2 "field lists" should be returned and * the 1st field list must correspond to the 1st Invoice and the 2nd * field list must correspond to the 2nd Invoice. */ public List<List<String>> fetchInvoiceCustomNumberingFieldLists( List<Invoice__c> invoices, CustomNumberingConfigurationSetting__c customNumberingConfigSetting) { List<List<String>> fieldLists = new List<List<String>>(); for (Invoice__c inv : invoices) { List<String> fieldList = new List<String>(); fieldList.add(inv.BillingCountry__c); fieldLists.add(fieldList); } return fieldLists; } }
To add the name of custom callback class, go to Setup > App Setup > Develop > Custom Settings and click Manage beside Billing Custom Classes. Click Edit for System Properties and enter the name of your custom callback class in Custom Invoice Numbering Callback Class.
