Number Series

A number series is used to maintain a series for numbering documents (like invoices)

Properties:

• name: Prefix of the series example INV-
• current: Its current (or starting) value. This will be auto updated everytime the series is updated.

API

You can get the next number in the series by using the utiltiy function

const model = require("frappejs/model")
let nextValue = model.getSeriesNext("INV-");

Setting naming series in a document

To setup a number series for a DocType:

• It must have its own "Settings" [single document](../models/singles.md. For example (InvoiceSettings for Invoice).
• The settings document must be set via the settings property in the DocType
• The settings document must have a numberSeries property with value of the number series
