Splitting Invoices Using an API

You can split an invoice into multiple invoices by calling the Apttus_Billing.BillingService.createSplitInvoices API. You have an option to choose between split by amount or split by percentage methods.

This API can split a single-source invoice into multiple invoices. To split more than one single-source invoice, you must exclusively call the API each time to individually split the invoices.

API	Signature
Apttus_Billing.BillingService.createSplitInvoices	static List createSplitInvoices(List splitInvoiceRequests)

The API accepts source invoice ID, split by amount or percentage, number of splits, as the required input parameters. For each SplitInvoiceRequest, a set of split invoices is generated in Draft status. You can auto-approve the split invoices by setting the Auto Approve Split Invoices to True.

Response

Field	Type	Description
CustomClass.SplitInvoiceResponse	List	A result parameter is returned for each request parameter.

When you split an invoice, the status of the source invoice changes to Distributed status. The split invoices are created based on the values provided by the user. Split invoices are created with the same number of invoice line items as that of the source invoice. The amount for the split invoice is distributed based on the split percentage or split amount. Taxes are recalculated based on the split invoices and Destination Related A/R Transactions are created for each split invoice.

The API returns an error message if:

The source invoice ID is not valid.
The source invoice ID is valid but the invoice is not approved.
The source invoice ID is valid but the invoice has a credit memo associated with it.
The source invoice ID is valid but the invoice is paid from a wallet.
The source invoice ID is valid but the invoice is already split.
The number of splits is an invalid value.
The “Split by” is null or has an unrecognized value.
The number of supplied values for “Split by value” does not match the “Number of splits” mentioned.
The sum of the percent values of all the splits is not equal to 100.
The sum of the split amounts mentioned in the split lines does not equal the total value on the original invoice.
“Auto approve the split invoices” or “Generate Invoice Lines Summary” does not have a valid value.
Details like Bill To, Location, Payment Term, or Invoice Date are supplied for a few of the splits.
