Create Child in Sales Invoice

Frappe Framework
1

Hi,

I have created a doctype that runs through some items that will trigger a creation of invoice. My parent is now working fine, but I am having trouble on child: Sales Invoice Items.

I’m getting error as below:

Error: Data missing in table: Items

Here is my code from my doctype’s python.

                            item = frappe.db.sql("""SELECT * FROM `tabUnit Charge` uc,`tabCharge` c
                                    WHERE uc.charge = c.name
                                    AND c.charge_type = 'Fixed Amount'
                                    AND uc.bill_run_type = %s
                                    AND uc.parent = %s;""", (self.bill_run_type, i.unit), as_dict=1)

                            for j in item:
                                    c_doc = doc.append('items',{})
                                    c_doc.item_code = j.item
                                    c_doc.item_name = j.description
                                    c_doc.descriptiom = j.description
                                    c_doc.qty = 1
                                    c_doc.rate = j.rate
                                    c_doc.amount = j.rate
                                    c_doc.base_rate = j.rate * doc.conversion_rate
                                    c_doc.base_amount = j.rate * doc.conversion_rate
                                    total = total + j.rate

I have no idea what is missing on the items. Please help.

Hi I think it should be like this

 SI_item = {
            "item_code": item_name,
            "item_name": item_name,
            "rate": line_item["price"],
            "amount": line_item["price"] * line_item["quantity"],
            "qty": line_item["quantity"],
            "warehouse": "Sales Order Default - SSC",
            "description": item_name
        }
        SI_items.append(SI_item)


 SI = frappe.get_doc({"doctype": "Sales Invoice",
                         # "name": test_order["number"],
                         "title": customer_name,
                         "customer": customer_name,
                         "posting_date": test_order["created_at"],
                         "due_date": test_order["created_at"],
                         "items": SI_items,
                         "apply_discount_on": "Grand Total",
                         "discount_amount": promo,
                         "taxes": charges,
                         "docstatus": 1
                         })
    SI_created = SI.insert(ignore_permissions=True)

Thanks for the reply John. Will try this out. All of my items are Services, WIll there still be a need to populate the warehouse?

I don’t it won’t be needing warehouse since they are Services :slight_smile:

Thanks John. By the way, the first sccript works now. I was actually creating a Sales Invoice without an item on my SQL query. Thanks.

By the way, I have been in contact with Chris Ian regarding some development works here in the Philippines. I think you guys are from same company.

Great! Yes you can also do it by sql.

Yes we are in the same company Bai Web and Mobile Labs. It would be best if we communicate in Slack, email to me jvfiel@bai.ph your email ad that you prefer to use in Slack, and we’ll invite you :slight_smile:
