What does your filter look like?
What happens if you remove it?

This is mu current filter

cur_frm.fields_dict['item_class'].get_query = function(doc) {
	return {
		filters: {
	      "is_group": 0,
	      "parent_item_group" : doc.product_type


Although when i add more item in the product type it shows this error.

I think the filter syntax you are looking for is like this :

cur_frm.fields_dict['item_class'].get_query = function(doc) {
    return {
        filters: [
            ["Warehouse", "parent", "=", "Wicked Widgets - LSSA"],
            ["Warehouse", "name", "!=", "Radioactive Widgets - LSSA"],

I hope I have correctly transcribed to older Javascript, I use ES6 so mine look like this:

cur_frm.fields_dict.from_stock.get_query = 
    () => ({ filters: [
      ["Warehouse", "parent", "=", "Envases Iridium Blue - LSSA"],
      ["Warehouse", "name", "!=", TS],
      ["Warehouse", "name", "!=", "Envases IB Rotos - LSSA"],

Of course, all that matters is the contents of the filters array.

hi i have adjusted the code it looks like some things like this

> cur_frm.fields_dict['item_class'].get_query = function(doc) {
>     return {
>         filters: [
>             ["Item Group", "parent", "=",doc.product_type],
>             ["Item Group", "is_group", "=","0"],
>         ]
>     };
> }

It is not filtering anything it doesn’t filter the parent of the item group based on the field product_type.

Did you find any solution?
