data = {
“payment_no” :“XYZ”,
“paid_amount” : self.amount_paid,
“out_standing_amount”:self.due_amount,
“paid_amount”: self.amount_paid,
“date_of_payment”: today()
}
self.update( {
“my_child_table” : [data]
} )

Hopefully this works !

Did you manage? I have a similar scenario to work on.

This replaces all data

My solution:

	self.childdoc = []
	data = []
	for loop
		data.append({
			"item": item.name,
			"quantity": quantity or 0,
			"amount": (quantity * item.price) or 0
		})
	self.update({
		"childdoc": data
	})

Hope it helps others.
