Filter child table based on parent value?

[ROHAN_JAIN1]

How can I filter a child field base on parent field in javascript?

use case:

I have a parent field item_parent and when I click to add a new row in the child table there is an item code which should be filtered base on the item_parent selected in the parent field.

any idea how to do this?

Filter Child items dependent on parent form

@Prashanta_Mahato There are query written in material_request.js as well as in buying controller purchase_common.js. So you have to either modified in material request js or override it by extending class. cur_frm.cscript.onload = function(frm) { cur_frm.set_query("item_code", "items", function() { return { filters: {"item_group": "Products"} } }); } Above script is working but I have to override the onload event. Try this with another method
