How to restrict supplier field on Purchase Order screen to certain values based on filter

Frappe Framework Custom Script
1

Hi There,

We are trying to restrict values in Supplier Link field on Purchase Order page to certain values based on a filter using below custom script but it doesn’t seems to work. Please help.

frappe.ui.form.on(“Purchase Order”, “onload”, function(frm) {
cur_frm.set_query(“supplier”, function() {
return {
“filters”: {
“currency_pay_in”: “USD”
}
};
});
});

We have defined a custom field for supplier called company. Once above script is working, we want to replace "currency_pay_in with company field and change “USD” to “cur_frm.doc.company”.

Please note we also have following onload custom script in addition to above for purchase Order doctype.

frappe.ui.form.on(“Purchase Order”, “onload”, function(frm) {
cur_frm.set_query(“expense_account”,“items”, function() {
return {
“filters”: {
“company”: cur_frm.doc.company
}
};
});
});

frappe.ui.form.on(“Purchase Order”, “onload”, function(frm) {
cur_frm.set_query(“cost_center”,“items”, function() {
return {
“filters”: {
“company”: cur_frm.doc.company
}
};
});
});

I have managed to get it to work by changing onload to refresh. What is the difference between the two?

frappe.ui.form.on("Purchase Order", "refresh", function(frm) {
    cur_frm.set_query("supplier", function() {
        return {
            "filters": {
                "currency_pay_in": "USD"
            }
        };
    });
});

onload is called only the first time the document is loaded on the screen, subsequent times, it is refresh
