const findEmployeeRole = (invoiceRec, scriptContext) => {
            try {
                let docArrays = [];
                let employeesWithRole = {};
                let lineCount = invoiceRec.getLineCount({
                    sublistId: 'time'
                });
                for (let i = 0; i < lineCount; i++) {
                    let apply = invoiceRec.getSublistValue({
                        sublistId: 'time',
                        fieldId: 'apply',
                        line: i
                    });
                    if (apply) {

                            sublistId: 'time',
                            fieldId: 'doc',
                            line: i
                        });
                        docArrays.push(docArray);
