Custom Batch Chain

In some business models, the standard batch chains as shipped with JustOn may not meet your requirements.

Using the custom setting Custom Batch Chain, you can override existing batch chains like, for example, INVOICERUN. The setting allows for including or excluding batch Apex classes and modifying their execution order.

Each Custom Batch Chain setting specifies the following mandatory information:

Field	Type	Description
Name	Text	Specifies the name of the batch chain to be modified. Use one Custom Batch Chain setting record for each batch chain.
Batches	Text (255)	Comma-separated list of batch Apex classes that are to be processed within the customized batch chain.

Checking batch chain configuration

You can check the configuration of a batch chain executing a script in the Salesforce Developer Console. To check the actual configuration of your INNVOICERUN chain, for example, run:

List<String> batchNames = new List<String>();

for (ONB2.ChainableBatch b : ONB2.BatchFactory.getInvoiceRun()) {
    batchNames.add(String.valueOf(b).substringBefore(':'));
}

System.assert(
    false,
    String.join(batchNames, ',')
);

Configuring Custom Batch Chain

To override a batch chain, you define a new Custom Batch Chain setting:

1. In Setup, open Custom Settings.
   In Salesforce Lightning, navigate to Custom Code > Custom Settings.
   In Salesforce Classic, navigate to Develop > Custom Settings.
2. Click Manage in the row of Custom Batch Chain.
3. Click New.
4. Specify the details as necessary.
   
   • Name: The name of the batch chain to be modified
   • Batches: The batch Apex classes to be processed
5. Click Save.

Info

Create an individual Custom Batch Chain setting record for each batch chain to be modified.

Custom Batch Chain example - INVOICERUN

You have configured the generic invoice run. When the invoice run is finished, you want all invoices to be finalized and sent out via email automatically without user interaction. Use the following setting:

Field	Value
Name	INVOICERUN
Batches	GenericInvoiceRunBatchHelper, BatchAssignBalances, SettleInvoicesBatchHelper, BatchFinalizeInvoice, BatchPdfGenerate, BatchInvoiceEmailQueue, BatchInvoiceEmail
