[6.27.19] Add item_name to Sales Invoice form

I would like to have the item_name showing in the sales invoice form.

Tried some options editing the Sales Invoice Item doctype, also tried modifying the
~/frappe-bench/apps/erpnext/erpnext/templates/form_grid/item_grid.html
with no luck

@gadiel

Did you check item name field settings in Customize form => Sales Invoice Item

Make sure its list view is selected. Its enabled by default.

it is checked,

does item_name shows in your enviroment?

@gadiel

Yes it is. But if you are trying this with custom doctype.
Go through below link https://discuss.frappe.io/t/how-to-use-saler-order-item-form-in-our-custom-form/12733/9

I’m doing it in the Sales Invoice parent doctype of Sales Invoice Item, but haven’t been able to check where do I pick which elements to show. Currently it only shows {item_code, qty, rate, amount}

thanks in advance!
