Here, I have taken the example to c<\/strong>hange the sequence of custom field before \u201csubtotal\u201d in invoice in Magento 2 backend<\/a><\/strong><\/em>.<\/p>\n\n\n\n In this example, the \u201cqty\u201d custom field is added and the sequence of \u201csubtotal\u201d changes as \u201cqty\u201d is placed in the first position.<\/p>\n\n\n\n Such changes in Magento 2 admin panel for invoice helps admin to get all the required details in invoice totals in the sequence of priority.<\/p>\n\n\n\n 1. Create registration.php<\/strong> file at app\\code\\Vendor\\Module<\/strong><\/strong><\/strong> directory<\/p>\n\n\n\n 2. Create module.xml<\/strong> file at app\\code\\Vendor\\Module\\etc<\/strong><\/strong><\/strong><\/strong> directory<\/strong><\/p>\n\n\n\n 3. Create sales_order_invoice_new.xml<\/strong> file at app\\code\\Vendor\\Module\\view\\adminhtml\\layout<\/strong><\/strong><\/p>\n\n\n\n 4.
