How to add a child table after creating a new document using frappe.new_doc() in JavaScript?

Here’s what I have so far:

Any help or examples would be greatly appreciated.

Hi @Jiri_Sir, Here I created a sample example of a Purchase Order to Purchase Receipt creation so check it. Client script: frappe.ui.form.on('Purchase Order', { refresh: function(frm) { frm.add_custom_button("Create PR", () => { frappe.new_doc("Purchase Receipt", {}, doc => { doc.supplier = frm.doc.supplier; // Set other fields as needed frappe.model.clear_table(doc, "items"); frm.doc.items.forEach(po_ite…

Thank you so much for the assistance! It’s working like a charm now.

Below is the updated code snippet I’m currently using:

@NCP Is there any way to set default values for all fields? For instance, if I add an item_code in the item table, is there a method to automatically set default values for all fields in the document, similar to triggering an event?

                    pr_item.item_code = po_item.item_code;
                    pr_item.qty = po_item.qty;
                    pr_item.rate = po_item.rate;

pr_item.item_code = "Item A";
pr_item.qty = 10;

try it.

Yeah, I’ve tried that, but it’s not working as expected.

if I set the default values programmatically, it would look like this:

if I add the values through the UI, it would look like this:

@NCP This is my current code snippet:

@gopikrishnan

automatically set default values for all fields in the document,

Use it.

frappe.model.set_value(row.doctype, row.name, "item_code", i.item_code);

@NCP Not working, I also cleared the cache and tried twice, but still getting the same result

my code:

Worked from my end.

@NCP The code works when run in the web console, but it doesn’t work when executed through the code

[gopikrishnan]

@NCP I tested it with a setTimeout of 1 second, and it worked. So my guess is that if I run this after the document is ready, it will work fine. Before that, it doesn’t work. Is there any way to determine if the document is ready
