Need to exclude the requestor from approving the change request

[suryaogeti1]

Hi All

I am using the flow designer for approval process but here i need to exclude the requestor from approving the change request, how can we achieve this. In rules section can we use both code and configuration, i have tried it is not working for me

(function execute(inputs, outputs) {

    // Get the Change Request record

    var changeGR = new GlideRecord('change_request');

    if (!changeGR.get(inputs.changeSysId)) {

        return;

    }

    // Determine requester (requested_by preferred, fallback to opened_by)

    var requester = changeGR.requested_by || changeGR.opened_by;

    if (!requester) {

        return;

    }

    // Remove requester from approval list if present

    var appr = new GlideRecord('sysapproval_approver');

    appr.addQuery('sysapproval', changeGR.sys_id);

    appr.addQuery('approver', requester);

    appr.addQuery('state', 'requested');

    appr.query();

    while (appr.next()) {

        appr.deleteRecord();

    }

})(inputs, outputs);
