Restrict Cancel Rights

Add a handler to custom_before_cancel event:

cur_frm.cscript.custom_before_cancel = function(doc) { if (frappe.user_roles.indexOf("Accounts User")!=-1 && frappe.user_roles.indexOf("Accounts Manager")==-1 && user_roles.indexOf("System Manager")==-1) { if (flt(doc.grand_total) > 10000) { frappe.msgprint("You can not cancel this transaction, because grand total \ is greater than 10000"); frappe.validated = false; } } }
