Hi,

I assume your flow trigger is RITM table

please update as this and test once

var sysId = fd_data.trigger.request_item.sys_id;

var tableName = 'sc_req_item';

var number = fd_data.trigger.request_item.number;

var url = '<a href="' + gs.getProperty('glide.servlet.uri') + '/nav_to.do?uri=' + tableName + '.do?sys_id=' + sysId + '">' + number + '</a>';

return '[code]' + url + '[/code]';

Regards
Ankur
