POS: select query for Items

Hi,
POS displays duplicate items when Item marked as Variant. Details explanation found in the below link:

(v11) Strange behaviour in POS with Item Variants (possible BUG)

I modify POS doctype in location …frappe-bench/apps/erpnext/erpnext/accounts/doctype/sales_invoice/pos.py

in function:

> def get_items_list(pos_profile, company):
> 	cond = ""
> 	args_list = []
> 	if pos_profile.get('item_groups'):
> 		# Get items based on the item groups defined in the POS profile
> 		for d in pos_profile.get('item_groups'):
> 			args_list.extend([d.name for d in get_child_nodes('Item Group', d.item_group)])
> 		if args_list:
> 			cond = "and i.item_group in (%s)" % (', '.join(['%s'] * len(args_list)))
> 
> 	return frappe.db.sql("""
> 		select
> 			i.name, i.item_code, i.item_name, i.description, i.item_group, i.has_batch_no,
> 			i.has_serial_no, i.is_stock_item, i.brand, i.stock_uom, i.image,
> 			id.expense_account, id.selling_cost_center, id.default_warehouse,
> 			i.sales_uom, c.conversion_factor
> 		from
> 			`tabItem` i
> 		left join `tabItem Default` id on id.parent = i.name and id.company = %s
> 		left join `tabUOM Conversion Detail` c on i.name = c.parent and i.sales_uom = c.uom
> 		where
> 			i.disabled = 0 and i.has_variants = 0 and i.is_sales_item = 1
> 			{cond}
> 		""".format(cond=cond), tuple([company] + args_list), as_dict=1)

Adding DISTINCT clause in the above select statement is not work. Also, I did not find POS in Doctype list (Setup->DocType/List).

Kindly let me know what is the correct way to modify POS in ERPNext.

Hi all,
I do not find the way how to correct this issue, and I think that this is not a big issue for foundation personnel to rectify. Or at least somebody from foundation has confirm this issue so that we will discuses the solutions.

To link to that would draw attention on what steps and options to take here to resolve this.

Thanks Clarkej, issue has been reported on github
