How to add a filter for Drug Code in Medication Table inside Patient encounter doctype ? I would like filter Drugs as Item Group wise. Is it possible ?? [1]

Thanks for the reply. I fixed it, wrote this code inside patient_encounter.js file: frm.set_query("drug_code", "drug_prescription", function() { return { filters: { //is_stock_item:'0' item_group:'Services' } }; });
