Customize Form View

Let us understand the ERPNext architecture before we venture to learn form customization tool.

ERPNext is built over WNframework. In this framework, each form is created as a table in the backend. Each table has field and properties are assigned to each field.

Like Sales order is a table, in which sales order fields are defined in rows as "Sales order series" and "customer name". Each of these field has properties like "label", "mandatory", "print hide" etc.

Sales order table:

	Field label	Mandatory	Print Hide	In Filter
Sales order Series	Series	(Check box)	(Check box)	(Check box)
Customer Name	Customer	(Check box)	(Check box)	(Check box)

To store more details of sales order like item detail, we have separate table called "sales order item" table. Likewise, taxes are the separate table in sales order. So, for sales order form, sales order table becomes parent and sales order item, taxes and sales person becomes child table.

Please find below the table structure of each form type.

Transaction	Table	Table Name
Quotation	Quotation	Quotation
	Quotation item table	Quotation Item
Sales Order	Sales order	Sales Order
	Sales order item table	Sales Order Item
Delivery Note	Delivery note	Delivery Note
	Delivery note item table	Delivery Note Item
Sales Invoice	sales invoice	Sales Invoice
	Sales invoice item table	Sales Invoice Item
	Sales invoice tax table	Sales Taxes and Charges
Purchase Order	Purchase order	Purchase Order
	Purchase order item table	Purchase Order Item
Purchase Receipt	Purchase receipt	Purchase Receipt
	Purchase receipt item table	Purchase Receipt Item
Purchase Invoice	Purchase invoice	Purchase Invoice
	Purchase invoice item table	Purchase Invoice Item
	Purchase invoice tax table	Purchase Taxes and Charges
Journal Voucher	Journal voucher	Journal Voucher
	Journal voucher item table	Journal Voucher Detail

With this, lets dive into the form customization tool. "Customize form view" is the tool which allows us to select a table and modify fields property as per your requirement.
You can find customize form view by going to:
Modules --> Setup --> Customize form view
